Seasons & episodes

Schizophrenic Michael Simms threatens Shelley Cooper with a knife and when the woman is later killed, Manson orders CO19 to shoot him, assuming Simms is the culprit. In the subsequent inquiry by the department of professional standards, who also subject other officers in CID to criticism, the DI's judgement is called into question by his own superior officer, and he faces the prospect that his career could be over.

Callum and Diane are called to the scene of a domestic disturbance, only to find Diane's neighbour, who has been knocked unconscious with an iron. It looks as if his wife is escaping from an abusive marriage, but all is not as it seems. Meanwhile, Smithy and Nate answer a call from a man who has been sold fake raffle tickets, but the teenage mum accused of the crime impresses the coppers enough to earn a second chance to sort out her life.

A limo driver of a fading pop star is suspected of raping a student found unconscious in an alley by Reg and Tony. Jo and Sam investigate the circumstances leading up to her rape. Elsewhere, Smithy encounters Leanne Samuels again, when he and Emma are called to disturbance at a mini market - only to learn she has lost her job after taking time off work to look after her teenage daughter's baby, and this time he's determined to make Carly see sense before Social Services take the baby away from her. Stuart prepares to makes a further appearance on a tv crime show.

Questioned for beating up schoolboy Paul Herriot, irate father Bryce Lucas admits to Ben and Mickey he did so because he had been sent a videotape of the boy sexually assaulting his daughter - a pupil at the same school. Further investigation uncovers a cycle of abuse involving the disturbed youngster, but his story doesn't quite add up and there are further shocks in store, even for Sun Hill's most worldy wise officers.

Terry and Jo investigate the serious assult of a man promoting a rock against racism concert. Heaton, anticipating trouble at the concert, has a very public run-in with the local MP, Paul Sagger, who crosses swords in a heated TV interview by fuelling tensions in the local community, in the lead-up to the rock against racism concert.

MP Paul Sagger is exposed as an antiques smuggler who owns artefacts looted from a Baghdad museum, but Manson is unsure of just how he is obtaining the valuables. Officers investigate the double-shooting at the rock against racism concert, and Grace discovers Heaton was one of the intended targets. Jo and Terry uncover a possible connection to the Bulldogs of Patriotism.

Derek Jacobs becomes prime suspect for the rock against racism shootings. Manson leads the investigation into the murder of Abdul Muntqim. The search for the gunman leads to evidence confirming that local MP Paul Sagger is directly involved in the illegal importation of artefacts - and Sagger's partner reveals how he smuggled looted goods into the country in her son's coffin. The case reaches a dramatic climax when the killer turns up unexpectedly at the station.

Stuart's driver Trevor Jones helps CID with useful information about a limousine operator who is rumoured to be supplying cocaine as part of the champagne service. Diane and Will respond to a call regarding a hijacked limousine, and Stuart investigates an assault on the driver's wife. Mickey volunteers to pose as a city banker and gather evidence against the villain, but has a few uncomfortable moments when it becomes clear his cover has been blown.

When Stuart's driver Trevor Jones and a female friend are badly beaten up, the detective sets out to link the attack to a mysterious drug dealer known only as the 'Postman'. Meanwhile, Nate and Ben answer a call to a disturbance at a cafe where a boy has had paint sprayed in his face. The assault has racial overtones and the discovery of narcotics at the scene provides a vital lead for the CID investigation.

Stuart is horrified to discover his trusted driver and friend is the mystery drug dealer the 'Postman', who plans to use him as his inside man at Sun Hill, using incriminating photos and unexplained payments into his bank account to blackmail him. Jo rumbles what is going on, but Stuart's efforts to put matters right just lead to greater danger. A drugs bust is thwarted by a tip-off, and Manson suspects a leak from within the team.

Alternate title: "The Honey Trap".

Disgraced detective Zain Nadir is interviewed about drug trafficking in Hayesend Prison, where he is serving ten years for perverting the course of justice, after Callum and Will discover the body of a drug addict recently released from prison. He agrees to help his colleagues infiltrate the gang involved. Jack is not sure whether he can trust his mole and fears the worst when a riot breaks out just as the police move in to arrest the operation's kingpin, Zain's cellmate Jason Forbes, who makes good his escape in the confusion.

Zain gets a frosty reception at the station when Heaton secures his release from prison to help Meadows with the recapture of escaped killer Jason Forbes, and Will can't help taking a swing at the man who callously disposed of Honey's body in a bid to save his own skin. Unsurprisingly, Zain encounters hostility from several of his former colleagues. The pursuit leads to a gunpoint showdown, giving Zain a clear choice between escape and doing the right thing.

New recruit DS Max Carter joins the Sun Hill team from CO19 to investigate a tip-off about an armed cash-in-transit robbery, only to find partner DC Perkins drowning his sorrows after the informant is killed for his pains. PCs Gayle and Armstrong arrest two girls for failing to pay their cab fare, and a catastrophic train of events is unleashed when it emerges they were carrying a deadly cargo smuggled in from Ghana - and their boyfriends want it back.

Sally and Tony are taken as hostages by the gun-men and John and Gina take charge of the situation to evacuate the station when an officer is hit by a bullet. Terry sleeps off his hangover in a cell and finds himself in a waking nightmare, trapped in Sun Hill with two murder suspects, two drug mules in a bad way and a pair of reckless maniacs threatening to kill if they don't get their girlfriends back.
