Mt. Thomas station is full of secrets. Maggie and PJ have come back from holidays deeply in love but determined that no one, especially Tom, will find out about their new relationship. Meanwhile, Nick and Adam have intercepted Dash's Confirmation Certificate as a fully-fledged constable in order to have it framed for a special presentation, and Tom and Chris are conspiring to organise a surprise celebration for Dash's 20th birthday. Into this web of intrigue comes a very distressed Elly Winslow, asking for police protection because her ex-husband, Danny Hobson, has just been released from prison in Queensland where he was serving time for sexually molesting his own son, and she is terrified that he will come looking for them.

Dash is somewhere out there in a bus with a group of school children, their teacher and an armed gunman, and the Heelers are feeling especially bad about it because they led Dash to believe that they've forgotten her birthday. When the bus is found abandoned, the Heelers must decipher both true and false clues in order to find the missing children.

Adam's mate, Wazza Tully, is in trouble; Mandy Barnes wants him charged with sexual assault after an incident at the Imperial where a drunken Wazza tried to grabs her breasts. Tom sends Adam to ""have a few words"" with his mate and warn him to stay off the grog - especially at the footy club fund-raising function tonight. The function features Justin de Carlo, an illusionist and stage hypnotist. All the Heelers are there, and some of them even find themselves up on stage as volunteers, as does Wazza. But when Justin suggests that his hypnotised volunteers go and kiss the person they fancy the most in the room, the whole town is astounded when Wazza heads straight for Adam and kisses him full on the lips! Although Tom is inclined to play down the situation the following morning, believing the less fuss the sooner it will be forgotten, Wazza demands police action, convinced that he has been tricked and defamed.

A new resident, Bob Barker, comes in to the station to report a burglary. This seems normal enough until Maggie and PJ realise that Bob has had, not his contents, but his whole house stolen. They go out to investigate the property which Bob claims he hasn't seen for five years (since his aunt left it to him in her will) and find only the stumps on which the house sat. The Heelers tell Bob and his daughter Pippa that they will chase up the matter but it could be difficult, considering the theft could have occurred any time over the past five years. Financially strapped, Bob wonders where he can now spend the night. Tom organises for him to work a shift at the Imperial in return for a room. PJ and Maggie get on the trail of the missing house but find every lead dead. The only local house moving company in town hasn't done that sort of business for years. The other avenues the Heelers pursue, such as crooks selling off the parts for money, are equally fruitless.

When a review team arrives in Mt. Thomas to decide if the station should be down-graded, the Heelers are thrown into a panic. It doesn't help matters that Nick is the subject of a ""Day in the Life Of"" by Tony Timms, and is doing his best to show that the life of a cop is a dull one. But then a woman goes missing and Tony starts to think that Nick is having an affair with her. Maybe Tony will get a nice, juicy article out of all of this... with Nick as the subject!

When a young man, Dean Hartley, is involved in an accident following a high speed car chase secrets unravelled. Dean admits to driving the vehicle immediately after the accident but later retracts the statement. PJ had taped the conversation and brings the recorder out to show Dean, but when he pushes the play button he finds that the tape is missing. PJ begins to investigate the tape theft but when he stumbles onto the true identity of Dean's natural mother he finds a secret much more shocking.

PJ has just received news that an Adelaide man suspected of brutally slaying his wife has used one of his credit cards in the area, so the Heelers should be on the lookout for him. PJ organises the team to alert all businesses in the area. At the pub Klaus meets Wade Knight, the man he claims caused the accident. Klaus tries to start a fight but is dragged away by Nick. Nick brings his father and Wade into the station. PJ and Maggie discover that Wade is from Adelaide - could he be the murderer? Dash aids PJ with the investigation into Wade's true identity. As they unravel his past they uncover a credit card scam that has penetrated both Victoria and South Australia. But the reason for Wade's crime is something no one has suspected and its discovery will put Dash in a life-threatening situation. Meanwhile, Nick is starting to feel really concerned about his father. Evidence is beginning to indicate that Klaus may be responsible for the accident.

PJ is stepping out in style - back in uniform as the Acting Sergeant. But this isn't the only change at Mt. Thomas police station. A new member has arrived; acting CI Deborah Hill and none of the Heelers seems able to make a good impression on her. Deborah is currently suing another member, Sgt. Bill Parker, for sexual harassment and tensions increase when she catches the Heelers talking about it behind her back. Deborah is taking over a case from PJ; a series a warehouse burglaries. PJ believes that a local, Johnny Rossitano, is behind them. He explains to Deborah that he has spoken to Rossitano's girlfriend, April, who has told him that Johnny has teamed up with two out-of-towners, Sean and Michael Murphy. The trio are planning to hit a warehouse tonight. Deborah doesn't think much of PJ's techniques or his information. PJ and Deborah continue to clash as they prepare to stake out the warehouse that night. Tom realises that something has to be done and so tells PJ to back off.

On the pretence of continuing their investigation into a farm vandalism case, Adam and Dash spy Nick having some trouble handing Zoe a ring box. Dash and Adam strain to see whether or not she accepts the ring but their view is obstructed. Could Nick be getting married? The Heelers' speculations about the probability of coming nuptials are interrupted by a distressing call. Zoe's horse has been hit by a car. Rushing out to the scene, Zoe is beside herself, wanting to put the horse out of its misery herself. Nick convinces her to put her target pistol down and leave it to the vet. Zoe's grief over the death of her horse is amplified when she is told that during the course of the Heelers' investigation they have spoken to a man at her home who claims to be her boyfriend, a Mr. Martin Bridport. Zoe flies into a rage - Martin had no right to be at her place, and he killed her horse! Martin denies everything but Zoe is adamant; her ex-boyfriend is the culprit.

The Heelers face some harsh realities when Dash believes she has stumbled onto a case of neglect. After nearly knocking down a child in the street, Dash searches for the child's mother who turns up hours later. Dash believes that the woman's gambling addiction has led to the neglect of her son. The mother is furious at the allegations and, in the face of very little proof, Tom tries to diffuse the situation. He explains to Dash that her job is to investigate crimes not accuse mothers of neglect. Dash approaches the social worker, Tim Ryan, who promises to look into the situation. But Dash won't be satisfied until the child is out of the woman's care. Meanwhile, Clancy and Leonie Freeman, an intellectually handicapped couple, are having trouble with their baby Rachel. Friends of the Heelers, they have been tricked into handing over all their money to a photographer/con man who seems to work just within the boundaries of the law.

Movie fever has hit Mt. Thomas with the arrival of two film producers, Rip and Jake Vaughan. They are intending to make a film about the town's local legend - an 1880's bushranger named Starvation O'Flynn. Meanwhile, one of the locals, Don Sparrow, is busy making a commercial for Keith Purvis and his new bulldozer ""Big Rodney."" This piece of film-making has not, however, captured the minds and hearts of the people of Mt. Thomas the same way as the Vaughans' soon-to-be epic. PJ's detective antennae go off the minute he encounters the Vaughans. He doesn't like them at all; but is it because they could be criminals or because he doesn't appreciate them gazing into Maggie's eyes? PJ's suspicion of the Vaughans increases when petty thefts are reported on locations they have surveyed for the film. Are they using the film as a front for a burglary racket? The crimes surrounding the Vaughans become more mysterious when Big Rodney is stolen and Don Sparrow goes missing.

Maggie takes on the responsibility of an assistant crown prosecutor in a criminal trial. Tom finds himself on the side of the accused, a woman charged with the brutal murder of her husband. The case seems like an open and shut win for the prosecution...but is it?

The Heelers' fears are realised when a woman suffering from Motor Neurone Disease is found dead. Her family's past pleas for her to be euthanised make Dr. Zoe Hamilton sure it was not the disease that finally ended her suffering. The Heelers begin an investigation into the death but everyone seems to have an alibi. The answers are closer than they think.

Strange things are happening in the Eventide Retirement Home. Valuables are going missing, one resident is found dead under mysterious circumstances and another endangers the lives of the others when he hallucinates after smoking marijuana. Are the two teenagers doing Community Service behind all the trouble? Or is there something sinister about Yvonne Dunn, the Administrator of Eventide, who seems to have a strange hold over her residents? Who's the person so desperate to get a place in Eventide that they're prepared to go to any lengths to get the existing residents to move to other Homes? As the Heelers investigate they learn that love is a powerful motivator for both young and old. But then the Heelers learn from Leila Clegg, also a resident, that there have been other thefts. Yvonne Dunn starts to look pretty suspicious herself. She claims she did not report the thefts because it unsettles the residents, and Eventide has lost several other homes recently.

A visiting troupe of boxers at the annual Mount Thomas Show causes headaches for the Heelers with brawling and a rash of pick-pocketing incidents. The boxers and their matriarchal manager, Bonnie Crossing, aren't the easiest people to get along with, or the most helpful. The Heelers just have to sit it out till the troupes move on. But it isn't that simple. When Adam and Dash go to talk to the boxers about the latest pick-pocketing incident, they are met with stirring and resistance. The situation culminates in Adam accepting a challenge from one of the boxers, Jimmy Cutlass, in what amounts to a grudge match. Tom is furious and forbids it. Dash and Nick, who both abhor boxing and see it as senseless and dangerous also strongly disapprove. But Maggie, PJ, Zoe and Chris can't see anything wrong with it, especially if it can be turned into a charity match to raise money for new mats for the local Blue Light Gym. Adam decides to go ahead with the match.

""Mr. Lucky"" is Enzo Fiorelli, a charming, charismatic and successful con man. Several years ago he defrauded most of Mt. Thomas' Italian community for everything they had, destroying their lives, ruining businesses and leaving a trail of grief and outrage. Enzo Fiorelli paid for his exploits with a long stretch in jail. Released, he inexplicably walked out of his witness protection program, blowing his cover forever, and returned to Mt. Thomas. The Heelers struggle to keep a lid on the community's righteous resentment for the man who caused so many of them so much pain. At first it's only hate mail, and then it's a brick through the windscreen of Enzo's expensive car… but then it's a bullet through one of his tyres. Is it the community? Is it Enzo himself, trying to get the Heelers to give him full-time protection? And why has he returned to Mt. Thomas, where there is so much hatred directed towards him.

Sally Downie, the woman in Tom's life, has been abducted and the Heelers suspect the same two violent criminals who are holding hostage the daughter of a local con man. But when the girl escapes, the Heelers realise they may have misread the situation. Sally is still in danger and Tom must lead a desperate search to save her life.

Adam and Dash find Tony Timms, intrepid reporter for the Mt. Thomas Gazette, dazed and injured on the riverbank while they are investigating a reported explosion. Tony's camera has gone but he won't say who attacked him or why he was there. But the Heelers get a clue after they attend a charity fish dinner at the Imperial, all of those who eat the fish come down with food poisoning. Could it be that the Mt. Thomas River is polluted? Sure enough, the Heelers discover some suspicious looking barrels in the river. But Doctor Zoe's tests show that the drum contents had nothing to do with the fish poisoning. Meanwhile, Chris reports that the Akubra hat containing the money collected at the charity dinner has gone missing. The suspects include Keith Purvis and his new lady love, a local pig farmer. Or was it Jeanie, the cook, resentful of the implication that she poisoned the fish? And how was Tony Timms and his keen youth trainee involved?

Dash is befriended by a stray dog, but when she brings it back to the station, it tries to attack Nick and generally causes havoc. When Tom orders her to send it to the pound, Dash defies him, becoming almost obsessively defensive of the animal. Could this attitude have something to do with the news she has just received about her medical condition? Instead of obeying Tom, Dash advertises on local radio for the owner of the dog to come forward. Unfortunately, two separate contenders appear and, judging by the dog's attitude, neither of them is the real owner. What is going on? Dog attacks have been reported in the area, and the Heelers suspect Dash's new canine friend is the culprit.

Tom is faced with a dilemma when a mother asks him to protect her son, a convicted felon who is back home after an early release. The boy was responsible for the particularly cowardly armed robbery of a local real estate office which traumatised the owner's wife so much that she later committed suicide. Her husband seems a reasonable man, but could he be harbouring feelings of revenge? Someone has to be responsible for the threatening phone calls and broken windows the family is getting. The Heelers question an old associate of the son's and, by chance, discover him to be in possession of a stolen police gun. The news almost immediately brings Detective Sergeant Ben Stewart, from Organised Crime, to Mt. Thomas. He has been on the trail of these stolen police weapons for the past two years, and is excited to have a positive lead at last. Ben Stewart fits in very well at Mt. Thomas - almost too well for PJ's liking as he takes an immediate shine to Maggie and wants to ask her out.

PJ is pressuring Maggie to get out of her date with Ben Stewart as they are driving along the road from the local tip, when they notice a car that has run off the road. As they radio for an ambulance, they discover the real cause of the accident - the driver has a bullet through his head. Ben is immediately interested, convinced the unknown gun seller from last week may have been involved. He is particularly interested in finding a bullet from the gun to see if it matches one that was used to murder a police mate of his two years ago. Unfortunately, the only available bullet is in the driver's head. But when Det. Sgt. Peppy Romano arrives from Homicide, Ben starts to act strangely. Obviously these two have a history, but it is one they are unwilling to share with the curious PJ and Maggie. Peppy almost immediately announces his chief suspect as being the new wife of the brain-dead driver, citing his reason as the large life insurance held by her husband.

When Maggie and PJ are called to a wealthy grazier's to investigate a wool theft they are greeted by a mob of naked sheep instead of the empty wool shed they expected to find. The grazier points the finger at an ex-shearer and old time rival, but Maggie and PJ discover he is not the only person with reason to dislike the grazier. Other suspects include the recently sacked manager of the property and the grazier's own daughter who has her own powerful reasons to resent her father. As they Investigate the theft, Maggie and PJ discover a secret love affair between the daughter and the son of the man he most despises, the ex-shearer. Could the two of them be planning to use the stolen wool clip to start a new life together? The boy is a talented pianist and Dash's mum, Beth McKinley, is leading a group of citizens raising money for him to study music overseas.

When a visiting detective is accused of murdering a petty criminal and drug user, Maggie and PJ find their relationship under great pressure. The dead man was a vital link in the case involving three missing police guns and the discovery of Det. Sgt. Ben Stewart crouching over his body leads to suspicion that he is the murderer. Stewart has made no secret of his feelings for Maggie and he turns to her for help. While Maggie believes in Stewart's innocence, PJ can only go on the evidence.

Nick questions his ability to continue in the police force when he is duped by a sexual abuse case, and then makes a bad call in another related case when a woman asks for an intervention order against her ex-boyfriend, but Nick merely asks the man to stay away from her. When the woman ends up in hospital with a broken neck and her estranged boyfriend attached to her spinal halo, Nick must devise a way to bring the man down without further endangering the woman.

Tom and Chris' longstanding friendship is put in jeopardy when Chris finds a fifty-year-old journal in her cellar. The journal appears to have been owned by a young woman and Chris discovers that it is the true account of a romance gone wrong and murder. Chris brings the journal to Tom, asking him to discover the identity of the murderer and bring them to justice. There are no names used in the journal, but nevertheless Tom works out that the owner is a local spinster - the last person you'd ever suspect of hiding a murder for fifty years. Now that the owner of the journal has been revealed, Chris wants the investigation dropped; she doesn't want to see this woman put behind bars. Tom isn't keen on throwing the woman in the cells either, but a murder has been committed and he has no choice but to continue with his enquiries. This puts Tom and Chris, normally allies, head to head, with Chris aggressively defending the woman and Tom bringing her in to face the murder charges.
