Summary: After an old lady is mugged, tension builds in Mt. Thomas. Thanks to Clancy, an eye-witness of the event, suspicion rests on a new family in town: the Baxters. The adult children, Matt, Troy and Tarni are brought in but nothing can be proven. Their father Barry, a softly controlling man, comes to bail them out and shortly afterward, Clancy is bashed.

Summary: It is the day after the explosion. The Mt. Thomas police station lies in ruins; Senior Constable Joanna Parish is dead, as is Clancy Freeman; and Grace Croydon is missing. While Tom recovers in hospital, PJ, Ben, Susie and Jonesy move into the new police premises where they are met with a surprise: Nick Schultz, now a Detective Sergeant in Homicide, has arrived to investigate the attack. And he's not the only one. Sergeant Mark Jacobs has arrived in town for a temporary post - or so he thinks. But Inspector Falcon-Price wants Jacobs to move permanently into Mt. Thomas, because he wants a person more suitable than Ben to take over when Tom retires. Jacobs is an intellectual, self-confident, ambitious man in his 40s and quickly shows authority as the group move into their new premises. PJ and Nick question 'Rocket' Turnbull, Tom's old war comrade, although he claims - and Tom agrees - that he couldn't get access to that much explosive.

He's an enthusiastic cowboy who l

Summary: Barry Baxter is on assault charges against Tom, and Chris is angry because she was forced to lie for Tom. She confronts him and then tells Susie that Tom needs help.

Summary: Tension is rife in Mt. Thomas. Joss and Kelly interrupt a girl who goes crazy in a store, and later find out that bad speed is being sold in the town. PJ and Nick are on bad terms over what they think of Tom's intentions, and Amy is just trying to get someone to let her help. Ben and Susie are acting professionally around each other, and Jonesy is annoyed about their dalliance. After clearing up the confusion about which Sergeant is for what (Ben is for Operations, Mark is for Administration), the DNA report comes back which concludes that Troy Baxter did meddle with Grace's car but, to prove he raped Grace, they must stop the funeral and take his body for DNA, which angers the Baxter family. Although it is proven that Troy did rape Grace, PJ begins to side with Nick that Tom may be overdoing it to suggest that the Baxters bombed the station. And - after Tom verbally assaults Barry Baxter - and suggests they are selling speed as well, PJ earnestly believes he has gone over the edge. In

Summary: The gruelling investigation of the attacks on the Mt. Thomas police continues, as Tom heads to Melbourne to investigate the man who sold the parts for the bomb. He links it to chemical dealer 'Doc' Parkinson, and is determined to prove that he provided the Baxters with supplies for both the bomb and the speed. Although Nick seems to be against this idea, he does join PJ and Amy - who everyone at the station is very impressed with - on another search of the Baxter property, during which time he plants listening devices in their home - which ultimately lead them to discover the truth. On a doorknock, Jonesy and Susie rescue an attractive woman named Donna from a rubbish skip she has been locked in, and Jonesy falls for her. That night at the pub, her former de facto lover hits him, and then claims that Donna took all his possessions, and is a con artist. Ben has been fawning over Susie a little too much, buying her expensive gifts, and she ultimately gives them back and leaves him unsure

Only Susie is suspicious of Donna, a suspicion seemingly confirmed when Jonesy's room is trashed. He arrests Theo, whom Amy recognises from her time in Melbourne - he was involved in an assault on a known drug dealer. Tom agrees with Amy, and refuses to give Donna police protection since she may be involved. Jonesy is not happy, pleading with the others and ultimately storming out of the station to go and personally protect Donna. The cops begin to consider that they've gone too far, but a defiant Tom stands firm - Jonesy had better come back, or he'll be out of a job...

Summary: Jonesy finds his career on the line as he attempts to protect Donna, and so he is stunned when he learns that she is a call girl. When they are attacked by Theo, and Jonesy claims that Donna was abducted, Amy soon doubts his theory - thinking that Donna faked her abduction. Susie soon joins in on this theory, after Donna tells her that she has Jonesy now, and Susie can never have him back. Although Jonesy is allowed to return to work, and attempts to patch things up with the others, he is still seeing Donna - and is stunned when she tells him that a missing man named Hugo Allen was killed by Theo, and that Theo is actually a hired hitman.

Summary: Jonesy is stunned when Donna tells him that the people who hired Theo to kill Hugo Allen were in fact the police of St. David's. As he goes about investigating secretly, he learns that the police have not been caring about Allen's disappearance. When Amy finds out about his investigation, he is forced to get Donna to talk to her. Donna confesses that Louis Chang, a restaurant owner in St. David's, runs an illegal casino from his restaurant and she was a call girl there. She was with Hugo when he found himself in trouble with Chang, and subsequently Chang had his police buddies order Hugo's death. She had a mobile phone with pictures of the casino on it, but it was stolen when Jonesy's room was ransacked. Amy believes Donna's story, but decides not to tell Tom in case he, too, is corrupt. Jonesy and Amy go to Chang's posing as a dating couple, but are interrupted by Inspector Falcon-Price and St David's multicultural police liaison Lucy Wu, who are also dining there. Jonesy suspects tha

Summary: Donna is once again missing, but this time when she turns up she is high on cocaine, and Amy and Susie are desperate to know where she got it from. Meanwhile, Chris attempts to get someone to listen to her when she suspects there is a person hiding in her pub, and late one night she and Joss investigate and discover her ex-husband, Terry Kennedy, in the cellar. Kennedy came through decades earlier with his shearing mates and married Chris while she was still the publican's daughter, before eventually running off. She wants him out of town, and Tom agrees. The rest of the station is busy as usual: the disappearance of a pig and a dog causes an uproar; Ben and Susie - who appear to have begun a sexual relationship - seem to be at odds over where they are going next: Ben clearly wanting to go further, Susie not so sure; and Lucy Wu has been popping up at the station. An angry Jonesy goes to see Louis Chang but gets nothing out of him, however later the mobile phone with pictures of the il

Summary: Jonesy is missing, and the general consensus is that he has run off with Donna. Only Susie is suspicious, and rightly so - since he has been shot and wounded, and finds himself being held captive by Louis Chang. Tom is at first unwilling to believe Susie, and is too busy with the investigation into police corruption into St. David's. Frustrated, Susie has no choice but to go undercover unoficially and Ben - of course - agrees to help her. Tom and the team investigate Inspector Falcon-Price but the evidence soon proves that he isn't guilty, and neither is Lucy Wu - who both Amy and Jonesy were suspicious of. As the day comes to a climax, Susie and Ben find themselves in a dangerous situation which they survive, but she ultimately breaks up with him. Jonesy has to do the same to Donna, and has her arrested. And Amy is stunned to learn that her friend Andrew Reid is the real corrupt cop at St. David's.

Summary: Mt. Thomas is inundated by a group of footballers, and it isn't long before a gang rape occurs, but what no one expects is for Tom's stepson Daniel to be implicated. Amy, in particular, seems to be particularly emotionally involved with the rape case. Meanwhile, Ben starts a dangerous spiral as he realises that Susie has truly rejected him, and he convinces himself that he is a failure as a policeman. While Ben contemplates suicide, he ultimately makes a noble choice by resigning and going to be with his children in Perth.

Summary: As the rape investigation continues, Inspector Draper arrives in town - worried that Tom is running amok. While Daniel evantually agrees to a DNA test, and is proven innocent, Tom loses his stepsons as they leave to live with their grandparents. Meanwhile, Joss, Jonesy and Kelly deal with a snake problem.

Summary: Sgt. Roy Holland arrives in town and Joss takes the opportunity to get on his good side and do more than paperwork. While Joss investigates a mother who gave birth on the side of the road but soon is suspected of lying; Kelly bonds with Roy, who worked with her father as young cops. But soon things get out of hand when he makes a sexual pass at her. Jonesy finds himself against the law again when a friend of his is accused of murder.

Summary: Kelly's rejection of Sgt. Holland sees him treating her badly and continually giving her abuse. Amy realises what has happened but Kelly won't put in a complaint. When she finally does end up deciding to tell Tom, it is too late - for Roy's heroic actions in saving a suicidal kid from a deadly situation have made him a hero. Meanwhile, after rescuing an attractive older woman from a bicycle accident, Joss and Roy recieve a dinner invitation which ends unexpectedly; and PJ and Susie suspect an inside job when they investigate a robbery at a veterinary clinic and end up unravelling a deep family secret.

Summary: Joss discovers that Fay has a jealous husband and decides to break it off, until she makes him an offer; after a difficult confrontation, Kelly confides in Susie about Roy - leading to their decision to teach him a lesson; and PJ and Amy comes to loggerheads over who to arrest in a burglary and arson investigation.

Summary: Joss attempts to break things off with Fay Tudor but she doesn't agree. What he soon realises however, is that he is attempting to break off with her because he actually likes the relationship for once. Kelly is riding high after she gets payback on sleazy Sergeant Holland, but it isn't long before he is trying his old tricks on another young woman named Shayleen, who is only 15. Tarni Baxter returns to town, and Tom is certain that she is desperate for vengeance after Tom's arrest of her family. While he and Tarni square off, he arrests her boyfriend Ryan for possession of drugs, only Mark is suspicious that he planted the drugs himself. Tom arrives home that afternoon to find his dog, Digger, viciously murdered. Kelly realises that Roy is dangerous and makes a formal complaint to Tom, who agrees with her and suspends Roy, who then threatens him. The next day Tom's rental car is found on a deserted road, completely destroyed by fire - and with a charred body at the wheel.

Summary: The cops attempt to come to terms with what appears to be Tom's death. Amy suspects suicide but PJ thinks otherwise and, upon learning that Tarni Baxter had no idea of the accident, the two are set back a bit as to who committed the murder. What they don't expect is to find Tom alive in a seedy hotel, and although they attempt to help him, they soon realise that he may have been responsible for the death of whoever it was in his car. PJ and Kelly attempt to prove Tom's innocence but Amy and Roy think he may have gone over the edge. When they discover that Roy Holland is missing, it becomes likely that his body was in the car, and the knowledge that Tom suspended him, and that Roy may have suspected Tom of planting drugs on Ryan Dekker, leads Mark to accuse Tom of murder. Tom, meanwhile, is crazy with rage. He threatens Tarni by promising to plant her hair on the car and implicate her. However Shayleen Burke soon confesses that her father killed Roy after he discovered everything about
