Adolescent Stephen Jameson doesn't know it but he's about to break out, and several other special teenagers, as well as two thugs, hope to find him when or before he does.

Stephen has been abducted from the hospital by Ginge and Lefty, who take him to the mysterious Jedikiah. John, Carol and Kenny attempt to locate him and get him safely back to the lab.

In the Tomorrow lab, Jedikiah lays in wait to catch Tomorrow People like flies in his web of technology.

John, Carol and Stephen recover to find Jedikiah has left, taking Kenny with him. They follow them back to the mansion in order to perform a rescue, only to discover Jedikiah has set a trap for them.

John and Stephen jaunt up to the cyclops' spaceship in an attempt to rescue Kenny, Ginge and Lefty. There they finally meet the cyclops and discover the real reason why he wants telepaths.

Jedikiah is recovered from space by Count Rabowski, who is already holding prisoner Peter, one of the Time Guardians. Jedikiah tricks Peter into transporting them to the 20th century so that he can get his revenge on the Tomorrow People.

Carol and Stephen jaunt to the Tower of London where they encounter Jedikiah, who takes Carol back to Rabowski's spaceship, hoping to use her as leverage with Peter.

Rabowski finally coerces Peter into opening another Time Arch, where Jedikiah sends Rabowski to assault the lab in a prelude to eradicate the existence of Tomorrow People for all time.

TIM jaunts John and Stephen back to the lab where Kenny attempts to revive them. Meanwhile, Jedikiah forces Peter to take them back to the 20th century one last time.

The Tomorrow People investigate a series of natural disasters which are threatening the entire planet. Meanwhile, Ginger and Lefty take a day trip to Clacton and encounter a sinister pier attraction.

Ginger is brainwashed by the mysterious Spidron, who puts him to work in his mine operation. Meanwhile, Stephen and Lefty return to the pier in search of their friend.

John and Carol return to the lab where they find Stephen has been returned safely, but no one has any memory of what has happened. Meanwhile, Steen returns to the pier to continue his investigation into Spidron.

The Tomorrow People and Steen must find a way to save the workers trapped in Spidron's collapsing mine workings. Then they must track down Spidron and Sandor and stop them escaping or the entire Earth will be destroyed.

John, Liz and Stephen sense the break out of a new Tomorrow Person, Tyso Boswell. Unknown to them, however, he has already come to the attention of Professor Cawston, who introduces him to the mysterious Colonel Masters.

Cawston agrees to help the Tomorrow People find Tyso by introducing Stephen to Masters; however, as soon as Masters takes Stephen away, John and Liz lose contact with him.

Masters is now aware of the Tomorrow People's existence and is determined to harness their powers. He tries to recruit Cawston to his cause, revealing the true fate of Stephen and Tyso.

TIM summons Chris to the lab where he is able to cure John. With the rest of their friends being held prisoner, Chris comes up with a novel way to thwart Masters' plans.

The Tomorrow People are visited by Timus, an ambassador from the Galactic Federation. He tells them of the planet Pyrie, where telepaths are oppressed by the servants of the alien Khultan, and asks them to go there to help them.

The Tomorrow People meet up with Tikno, the clone brother of Timus who is on Pyrie for the same reason as them. He takes John and Stephen to meet the local telepaths, the Vesh, to try and persuade them to join forces.

Liz, Tyso and Lenda have been captured by the Veshtakers and sentenced to burning. While Stephen and Arkron try to rescue them, John, Tikno and the Vesh infiltrate the Khultan's pyramid in an attempt to restore everyone's powers.

A group of aliens stop off on Earth for supplies, but since their only knowledge of Earth's culture comes from watching cowboy films, it is not long before their visit results in violence and the Tomorrow People become involved.

The Tomorrow People attempt to rescue Elmer from the police and return him to the ship, otherwise his family will destroy Earth in retaliation.

The Tomorrow People persuade the British authorities to turn Elmer over to them so they can return him to the ship, but unknown to them Emily has plans for John.

When one of his colleagues goes missing after an expedition to Egypt, Professor Cawston goes to the Tomorrow People for help. They soon realise the expedition unearthed Jedikiah, who is attempting to track them down.

Tricia takes Jedikiah to the EWE, where he kills Colonel Masters. As a result, the EWE start hunting for the Tomorrow People.
