Still a captive of the Nomads, Sundance and Noah come face-to-face with the protectors once again and we discover that Sundance has a twin brother Sutch who is a Protector. To prove he is no danger to the Nomads, Noah detroys the sentinel and then both he and Sundance return back to the Nomad camp. Back at North Col, Dr. Pretorius and Becky are trying to re-trace what Noah did in order to find him and bring him back.

Noah and Arushka stare gob smacked at the huge creature before them. This is a circus in 1999 — they have gone back too far! Arushka doesn't hear or care about Noah's concerns — these are real animals not just images on a wall. She never wants to leave. Noah tells her in a couple of years the animals and everything else will be gone when the Nemesis Comet strikes. Noah sets off to find a power source, leaving a saddened Arushka to look around. All of the animals are amazing but when she meets the beautiful circus horse Moshi she is totally captivated. As Noah drags Arushka away from the circus they meet Sophie and Mingus, a pair of animal liberationists set on freeing the circus animals. Whilst trying to prevent the animals from escaping, Noah and Arushka are caught and accused of the break-ins. In North Col, a quantum aberration convinces Becky that Noah may have time-travelled. Tao roars across the Red Desert in the Beast, telling Jett about his latest weapon — the mobile Sentinel tracking device. They can run but they cannot hide! Noah and Arushka are being escorted to a waiting police car when a lion escapes its cage. The crowd panics but an entranced Arushka is captivated by the beauty of the King of the Jungle.

With the scaped lion on the bonnet of the police car, a horrified and amazed crowd watches as Arushka calms him. She achieves instant star status when she gestures the animal back into his cage. Ivana arrives with Moshi and speaks quickly with Arushka. She understands the future Arushka comes from and asks Arushka to take Moshi with her. Using power from a nearby news van, Noah activates the PH-Ts and in a flash of white light Arushka, Noah and the beautiful black horse Moshi are gone! Instantly they reappear in Haven and the first animal brought through time has arrived! Becky, experimenting with her own PH-Ts hoping to discover what happened to her brother, shrieks with delight as she witnesses their time journey. He's alive! Pretorius quizzes Becky about what she saw but he and Beck'y parents give little credit to her story. Becky wants to try to recreatd the conditions at the time of Noah's disappearance but is not allowed. Lost without Arushka's leadership, the Nomads, spotted by Tao's mobile Sentinel, are captured as they flee to safety. Noah, Arushka and Moshi launch into a rescue mission. Noah hijacks the Beast while Arushka liberates her friends. The Protectors are closing in on Noah when Arushka and Moshi gallop into the fray and scoop Noah from the Beast and on to freedom! Arushka fears that Moshi must not be the only animal in the future of the world. She tells Noah if he helps her she will help him get to a power source to effect his escape home. What choice does he have?

Tao has a plan to capture the Nomads — with the help of his Sentinel he will trap them in their own lair! In the Beast he watches on the screen as Arushka and Chip release Moshi and Noah and Geneva head towards the Mine. He and Jett race across the Red Desert chasing the signal, closing in. Noah and Geneva manage to hide just in time, thwarting Tao. But inside the Beast Sutch continues to record the Sentinel's readings, logging the caverns entrances. Tao outlines his plan to Sutch and orders more Protectors and supplies of Thunderstone. He will get them this time! Having secreted himself in a Protector vehicle returning to the Beast, Noah is shocked as a hand grabs him. Its Sundance. But now they are both trapped as protector guards surround them!

Still trapped under the Beast trailer, Noah and Sundance see Arushka approaching on Moshi. Tao, impressed with her bravery, and interested in Moshi, steps out to confront her, giving Noah and Sundance the chance to get inside the Beast trailer and sabotage the map co-ordinates that would lead to the capture of the Nomads. With the mission accomplished Noah and Sundance say their farewells, Noah heading off to the Keep and a power source for hs PH-Ts. Tao dispatches the Protectors, offering a reward, to whoever captures Noah. The glittering prize of a vehicle all the incentive they need. Alone, Tao tries to contact the Shadowmaster but with no answer — he storm out. With the Nomads safe again for the moment, Arushka heads to the Mine where Noah has been captured by Jett. Quick thinking gets Noah and Arushka into the Beast trailer. Accessing the power source, Noah grabs Arushka's hand ad they white-out as a volatile Tao rips the door open. Where are they now?

Arushka, still trapped in the past and hunted by Bully, Mac and Duane, saves Mac from being trampled by a wild brumby. Awed by the mystical effect she has on the animal, they listen to her story. Duane and Mac agree to help her but Bully standing alone is not to be trusted. Tao has dispatched his Protectors to Noah's arrival co-ordinates. As they close in on Noah, Dolly sends them scattering, terrified as they have never seen a monster like this dog. Noah must get to a power source and go back and save Arushka… who is with Duane and Mac rounding up horses when Noah whites-in. In a race against time, Bully having called the police, Noah powers up his PH-Ts and he and Arushka, now astride one of the horses, white-out. Tao is preparing to demonstrate his dominance over the animals that have his troops cowering when Noah, Arushka and the horses arrive in a whirlwind of light and dust and power. The Protectors again run scared from these strange beasts. More animals have arrived in Haven!

Arushka now has the horses she wanted but Noah tells her he can't help her bring back more animals to Haven — he wants to go home. Bidding them farewell he heads off towards the Mine. On the way a brave and loyal Dolly saves him again and his journey must be abandoned. The Shadowmaster exerts his power. Tao must mine more Thunderstone! He orders Tao to leave Noah to him, he has a plan! The Nomads have made their way back to the Cavern, but unknown to them, lurking in the darkness, following and watching their every move is Ferris. The Triumvirate summon Noah's family and Dr. Pretorius to appear before them. The charge is one of unauthorised scientific experimentation. North Col's strict laws must be obeyed if they wish to remain part of the community. As the sun rises on a new day Noah wakes from a dream of a world full of animals. He forges a pact with Arushka — together they will save animals from past and bring them to the future, to Haven.

In the middle of the red desert a furious Tao stands before a burning effigy of himself. Unguarded, the Beast's trailer looms behind. Noah and Arushka enter it and begin the first of many risky sorties to access the power they will need to bring back the wondrous collection of animals that will fill the magnificent landscape that is Haven. When the mission is accomplished, it is time for Noah to leave but Tao's tightened security will make this the most dangerous attempt of all for Noah. Ferris, fleeing from an unexpected meeting with Dolly and her new-born puppies, is captured by an equally nervous Savage and Rork. They gather up the puppies and head to the Keep with Ferris where Tao is demonstrating the Electronets — his latest weapon in his war against the Nomads and now the animals as well. Using this distraction to his advantage, Noah sneaks into the mine but is himself a victim of the Electronet. Tao has finally captured Noah, who still a little stunned yet still refuses to talk. But Tao has Dolly's puppies, and unless Noah co-operates, he will harm them with the Electronet!

Noah has been forced to give in to Tao, who would have used the destructive Electronet on Dolly's puppies. Now a prisoner in the Keep, Noah discovers Ferris and retrieves his PH-Ts which Ferris has stolen. Noah escapes with Ferris' help only to find Arushka has been captured while trying to rescue the puppies. Noah tries to smash the Net which Tao is trying to lure Dolly into but he is zapped and thrown to the ground, unconscious. The captive miners are galvanised into action and while the battle rages Sundance and Chip get Noah out, but Ferris is caught — and this time he'd better tell Tao where the Nomads hide! Tao's army, spearheaded by the Beast, races towards the Nomads' cavern. Noah and the Nomads are trapped — Jett's Thunder-oil smoke machine will flush them from their network of tunnels. This time there is no escape!

Noah and the Nomads are forced from safety by the Thunderstone smoke that continues to billow out of the Cavern; they are surrounded by Protectors and trapped by the Electronets. If captured they will be unable to stop Tao so Noah, their only hope, must travel back to his time and return with technology to fight the Electronets. Harnessing the power of the Electronets, he takes Geneva's hand and they white-out, arriving in the raging blizzards of Topside North Col where they succumb to the freezing conditions. Tao surprises the Nomads by releasing them, explaining that with Noah gone they are no longer a threat. He has called a truce — but why? Found by Dr. Pretorius and nursed back to health, Noah and Geneva are called before the Triumvirate for a preliminary hearing. There are a lot of questions that require answers and as there is no evidence to prove time-travel — the matter will need to be investigated in depth. Noah placed under house arrest and a frightened and confused Geneva is detained in the Discipline Centre.

With Noah and Arushka safely imprisoned in the Beast, Tao roars off leaving Chip alone under the relentless sun of the Red Desert. On a rescue mission, Sundance and Becky find him, exhausted and thirsty but alive. A smug Tao, with Noah his captive audience, tempts him with knowledge of his future; Noah is only 65 years in the future and he along with the survivors from North Col could still be alive somewhere. Tao produces a disk that he claims was found in the ruins of the old holodeck and contains a history of North Col. Noah agrees to watch it but only if Arushka is with him. The end of North Col unfolds — his family's suffering because of his illegal time-travel, the horrors of the rat carried disease rabies sweeping through the panicked citizens. Is he responsible? Noah believes he is the only one who can save his people — he must return. "But if I am the only survivor", asks Noah, "what happened to me?" Tao has one more piece of information… "you reappear", he says, "as the Shadowmaster!"

Tao offers Noah a share of the rabies vaccine and power to return to him to North Col. With Noah gone and the maserguns to rid Haven of the animals, Tao is now free to find more Thunderstone. Noah and Becky return to North Col, but where is everyone? What is happening? Was Tao right? They find Dr. Pretorius who confirms Noah's fears, rats have been sighted in North Col. Producing the vials of vaccine given to him by Tao, Noah tells Dr. Pretorius everything. Until the vaccine can be tested Dr. Pretorius advises them they must hide, there's nothing he could do if the Triumvirate found them. In Haven, Tao has the breakthrough he needs, a lead to a strong concentration of Thunderstone in the mountains. But the Sandtriber presence there must be eliminated. Marshalling his Protector forces, they move out in convoy. Nothing can stop him now!

The thought that he could be the monstrous Shadowmaster tortures Noah as he waits anxiously for the results of his father's tests on vaccine. When Becky produces the disk she took from Tao detailing apocalyptic future events, Noah calls for an Open Forum in which the citizens of North Col can decide on this evidence for themselves. If he can convince them to listen, he may be able to save them. Tao feels they are near the source of the Thunderstone — the motherlode! He will not be hindered by anyone or anything. As he prepares to fire on some horses, the Silverwing swoops through the air, disarms his masergun and returns to Sundance. The beautiful animals are safe. An enraged Tao orders his troops to move in. Faced with the Protectors' new weapons, the Nomads are surrounded. Noah has failed and he and his family are placed under house arrest. With Becky's help he eludes the holocops escaping to Dr. Pretorius retreat only to be confronted by the Shadowmaster. This time the nightmare is real.

Noah cannot believe that he is, or that in the future he will become, the creature that stands before him. The Shadowmaster tells Noah that it is time he learnt the truth. They both white-out of North Col and arrive in Haven. The Shadowmaster challenges Noah — was it right to bring the animals to Haven? They outnumber the humans and will continue to breed. Good, says Noah defending their rights and place in the laws of nature. The Shadowmaster lauds the wonders of Thunderstone. Its power will bring the human race back to his former greatness! It cannot be wasted on animals. "If I am to become what you are", says Noah, "why can't I change the future and so change myself? What is happening to me? To the Nomads?" But the Shadowmaster sends him back to North Col, back to rats scurrying everywhere, panicking citizens who don't see, as does Noah and his family, that the rats are in fact an illusion — they are holograms. Into this pandemonium the Shadowmaster appears and laughing mirthlessly, removes his mask revealing himself… it is Dr. Pretorius, he is the Shadowmaster!

The Daniels family are blamed for the rabies virus and the North Col community will not listen as Noah tells them the rats weren't real but holograms. Matters worsen when it is discovered the vaccine held as evidence has been stolen. Simon's subsequent collapse causes everyone to panic… he has a virus! Liz finds that the disk given to Noah by Tao is nothing but a series of sophisticated computer generation images. Who is responsible for this dangerous hoax? Noah returns to Haven to collect more vaccine to save his father. But the Mine has been abandoned. Tao has moved everyone to the Mountains of the Moon in search of the Motherlode. Noah makes his way across the Red Desert. He must save his friends and get the vaccine before it is too late! Inadvertently a Kestrel gives Tao the answer he has been searching for. Now the Shadowmaster and Tao stand, transfixed — before them is the secret of life, youth, and absolute power… it is the core of the Nemesis Comet… the pure Thunderstone Motherlode!

While the unsuspecting citizens of North Col are preparing for their journey to Haven, the Shadowmaster is assuring Tao that a labour force will arrive soon to help in the mining of the Thunderstone. Becky's suspicions are aroused when she sees Dr. Pretorius behaving strangely. As she explores a deserted North Col she discovers that Dr. Pretorius has the missing vaccine in his secret lab. Captured by the Shadowmaster she is forced to join the others in Haven. Noah unmasks the Shadowmaster revealing him to be Dr. Pretorius. Noah is not the evil Shadowmaster. Forced by Dr. Pretorius to listen to his great vision of a new Haven, they arrive at Tao's base camp just as the recaptured Nomads are herded in. An argument erupts between Tao and Pretorius and to prove his authority Dr. Pretorius exiles the Nomads… through time into the snowy blizzard of North Col.

In a Topside blizzard the bewildered Nomads make their way into North Col where Geneva guides them to the holodeck. Through a combination of deduction and good luck the Nomads propel themselves forward in time to Haven where their reappearance is monitored by Sutch. Sutch, who is under instructions from Dr. Pretorius to take Noah and Becky to a place they can never return from, instead reunites them with the Nomads. He too will now join them in their battle to defeat the Protectors and Dr. Pretorius. Together they formulate a plan to destroy the Thunderstone. Noah and the Nomads move on the unprotected Thunderstone motherlode. As Sutch and Sundance hijack the Beast and liberate the enslaved work force, Noah, Becky and the other Nomads spread salt out at the motherlode base. The showdown has begun! Tao and Dr. Pretorius move to protect their Thunderstone, their future. Tao, now revealed to be a hologram himself has targeted Noah but Becky's quick thinking saves him. Tao flickers wildly and disappears! Dr. Pretorius, his life's work destroyed pleads with Noah who, raising a Masergun, ignites the salt and with it the motherlode. The war over, Noah throws down the Masergun. Behind him Dr. Pretorius is left engulfed by the flames. Tranquillity in Haven, the Nomads and animals are free. Noah, his family and the citizens return to North Col — there must be a past so there will be a future. As Noah hangs up the PH-Ts he smiles with the memories he will hold on to. In Haven Arushka rides proudly on Moshi. Before her the landscape is filed with the animals of the world. They will live free once more.

In Haven of 2085, Arushka rides Moshi, her black mare, through the Riverlands. She's inspecting the contented Animals which she and Noah have transported to the future to avoid extinction. Dolly follows at a distance… But we see the faithful sheepdog distracted and lured away. Above the North Col of 2020, the Impact Winter produced by the Nemesis Comet still prevails. Noah discovers Dolly, terrified and half frozen in the blizzard. How had the dog travelled back through time and who sent her? Arushka returns to the compound, where the Nomads now live as a settled community. With their enemies vanquished and the contentious mineral Thunderstone wiped from the face of the Earth, Haven is a peaceful place. An eccentric old peddler, Monsoon, visits with gossip about the comings and goings of new settlers and about the weather, which in Haven has lately been extreme and unpredictable. Dolly is discovered in North Col by the authorities and is condemned to banishment in the snow. To save her, Noah breaks the new rules which ban time- travel. He breaks into the sealed Holodeck and used the PH-Ts to return again, with Dolly, to Haven. He arrives at the height of the storm and helps the Nomads save their hut from a lightning-felled tree. Then there's time for a reunion. But the Dolly mystery is unexplained and some unidentified figures are watching them through the trees.

-Noah is quick to notice that there is dissent among the Nomads. Now that they're no longer on the run from a common enemy there's a restlessness. Old Monsoon visits with his wares and tall tales and wheedles an invitation to stay the night. In the morning, Noah discovers he's taken his PH-Ts and he and Arushka set off to the get the precious time travel device back. Meanwhile in North Col, Becky tries to cover for Noah's absence by producing the Noahgram, a hologrammatic version of himself which Noah has recently created. Its behaviour creates bizarre situationsand the ruse is quickly discovered. Chip, annoyed at being left behind, determined to catch Monsoon by himself. Against Kwan's warnings, he saddles up Moshi, Arushka's majestic black mare. Arushka and Noah catch up with Monsoon and demand the PH-Ts returned, but the crafty old man denies having seen them. Meanwhile, Chip is having trouble with Moshi—but he hears the rattle of Monsoons pots and pans in the distance and manages to spur the horse on … into the woods. All is silent and there is no sign of Monsoon, but something in the bushes frightens Moshi. She rears and Chip is thrown into a pit of quicksand. The frightened horse bolts, leaving Chip alone and helpless, sinking further into the quagmire. What could have frightened Moshi so much she'd leave a Nomad in Peril? Alerted to the danger by Moshi, bridled but riderless, Noah and Arushka race to Chip's rescue. But they're too late… as Chip disappears below the sand four strangers to Haven haul him out—Myah, a barbaric looking young woman and her three brothers, Rorden, Tod and Lyal. Not only have they saved Chip's life, they also have the PH-Ts, which Rorden reluctantly relinquishes. The Nomads and the new family pledge a wary friendship. With the PH-Ts returned, Noah must face the fact that there is no source of power for them in Haven. How will he get back to North Col?

-As dry electrical storms prevail in Haven there is growing concern about the changing climate. Noah devises a plan to harness the lightning, which strokes most often on Razorback Ridge, and so powers his PH-Ts. Monsoon wins back favour in the Nomads' compound by bringing in a wounded animal and half of a weathered amulet. Kwan produces the other half, given to him by his long-lost mother. With the prospect of reuniting with her, Kwan bids the Nomads farewell. Though his hopes are dashed, a heart-broken Kwan has too much pride to return to the compound. Monsoon, meanwhile is spooked by a visit to the family. It seems these people can communicate with each other telepathically. Up on Razorback Ridge, Arushka insists Noah test the PH-Ts before using them on himself. The stand-in scarecrow is burnt to cinders as lightening is channelled into the PH-Ts. Nevertheless Noah ignores all protests, reconfigures the equipment and successfully time-travels back to North Col. Noah's family are relieved to see him but the North Col authorities thrust him into the detention centre for breaking the time travel ban. Myah is lurking in the North Col sludge pipes. How and why has she accompanied Noah on his time travels?

Myah makes herself known to Becky and Russell, a clumsy classmate whose suspicion is quickly supplanted by infatuation with the stranger. When the news is conveyed to Noah he realises he must take her back to Haven immediately. But how to escape the detention centre in order to do it? Russell reluctantly agrees to help by taking Noah's place in the cell. Bamboozling the Holocops, Becky smuggles Russell in and Noah out. Meanwhile in Haven, Lyal pays a visit to the Nomads' compound. His bullying and arrogance infuriate Sundance and he gladly accepts when Lyal challenges him to a race. Sundance is further angered when Lyal wins by cheating and with help from his brothers who secretly use their telepathic powers against him. It's memorial day in North Col. Syndia, the most officious member of the ruling Triumvirate, is giving her address. With everyone distracted Noah and Myah make it up to the holodeck. Myah shows an over zealous interest in the workings of the Holodeck as Noah successfully white-lights them out. By now Russell has been discovered. A furious Syndia strides into the detention centre and sees Noah is gone. Noah is now in deeper trouble then ever. Back in Haven, he and Nomads view Myah and her brothers with increasing suspicion.

Syndia, still fuming, pronounces banishment for Noah when he returns. In Haven, Noah is awaiting the next lightning strike. Myah pleads with him not to leave, making vague promises of power and success. She is left behind angry and frustrated, as Noah white-lights out once again. Noah arrives home secretly and employs Becky's radical plan to avoid banishment: he uses the PH-Ts to travel 24 hours back in time to the detention cell. In the re-run yesterday, Syndia storms in and finds Noah safely locked away, rather then discovering Russell. Back in today, Becky is delighted with the success of their plan, but Noah is shaken by its implications. He swears never to use time travel technology to change history again. Meanwhile in Haven, Geneva falls into an animal trap — who would make such a thing in Haven? Chip runs off to alert the others but doesn't see a herd of wild brumbies approaching. While Lyal and Rorden muster the animals towards the trap, Tod, the youngest of the family, discovers Geneva and places himself between the trap and the stampeding animals. He manages to divert them and pulls Geneva to safety. When they spot the Nomads approaching, Rorden and Lyal flee. Tod is brought back to the compound as a prisoner. As a hunter of animals he is an enemy to the Nomads. But his charms are not lost on his warden, Geneva. She is convinced Tod has learned his lesson and successfully argues for his release. At their campsite, Myah rips into her brothers for getting on the wrong side of the Nomads. They need them… but for what?

There has been no rain in Haven for a long time and Arushka is worried about the animals. While checking up on them she sees Rorden, the most eccentric of Myah's brothers, scurrying out of the rocks below Razorback Ridge. She and Sundance return to the spot to investigate. They discover Rorden's Grotto, filled with weird equipment. Meanwhile Myah is conducting a few investigations of her own. Once again she uses the Nomads goodwill to her advantage and is snooping around the Beast, an old vehicle still filled with gadgetry of its precious owners, the Protectors. The brothers return to their cave and catch the unsuspecting intruders. Arushka and Sundance have no means of escape, locked in a primitive cage. What is the strange family up to? Above North Col, Noah finds a pair of modified PH-Ts, exactly where Dolly was found. Somebody, sharing his knowledge, must have sent her into the past deliberately. Risking the inevitable censure, Noah once more travels to Haven to find the truth. The Nomads have received Arushka's message from Prince, a friendly kestrel. Noah and the gang embark on a mission to rescue Arushka and Sundance. In the struggle between the Nomads and the brothers, Sundance is recaptured. And now Rorden has got hold of the PH-Ts. At last, he says, dangling them in from of the caged Sundance, I have a human subject for my experiments.

Rorden prepares to send Sundance on an experimental time trip. In a failed rescue attempt, Chip is caught up in the white- light along with Sundance. The two boys arrive in a present day dance club. Chip is fazed by his surroundings, but Sundance finds the rhythm of the music intriguing and has soon caught the eye of a pretty girl. Myah returns to find the brothers in a panic and is furious about their inept behaviour. Not only have they damaged the family's relations with the Nomads almost beyond repair, but Myah is forced to ask for Noah's help in retrieving Sundance and Chip. Noah's assistance is not cheap — Myah has to answer his questions. Myah reveals that she and her brothers come from the Silver City, a future metropolis — the pride of Haven in 2235. Noah extricates Chip and Sundance from the club, just in time to avoid the wrath of a jealous boyfriend. On Razorback Ridge, Myah and her brothers are part of a welcoming committee, but the Nomads want nothing to do with the meddlesome family.

Drought conditions in Haven are at a crisis point. Desperate to give the precious animals the best chance for survival, Arushka and the Nomads attempt to muster them from the vast, parched high country into the lowlands. A scrub fire breaks out and the frightened animals are scattering when Myah and the brothers appear offering help. Together with the Nomads they manage to put out the fire and herd the animals to a lowland area where there are still a few patches of pasture. Arushka and Noah warily agree to hear Myah's suggestions for a more permanent solution to the drought. She explains that in Silver City of 2235 their father was in charge of a weather control system and that they have landed here as a result of Rorden's fallible experiments with time-travel. Rorden unveils the futuristic blueprint for a rain machine and Noah is astounded to realise the building of such a thing is feasible. But with Thunderstone eradicated from Haven there would be no source of power gigantic enough to drive this machine from the future. Back in North Col, Becky discovers a storeroom filling with steam. She is struggling with valves and overrides switches when Liz, her mother, comes to the rescue. Something is wrong with the exhaust line, which Liz believes could indicate serious problems with North Col's foundations. In the Haven compound the Nomads are mulling over the impasse with the rain machine. Monsoon arrives with tales of a distant valley, high in the mountains beyond, where the Nomads have ever ventured. Legend has it that it is home to a huge cube of pure Thunderstone. The Nomads agree on an excursion there. They have to find out if the Thunderstone cube is more then a myth. It could be the key to saving the animals. The relentless trek upwards in the heat seems to be fruitless. The thirsty Nomads eventually find the mystical Valley of Chazon, but instead of a Thunderstone cube, there is a great lake in the valley floor. Arushka collapses by the shore in despair when she discovers that the clear blue lake is salt water.
