Seasons & episodes

PC Dave Quinnan returns to duty, and is determined to prove to everyone that he's back to normal after his breakdown. Out in a panda car, Quinnan sees a man shot in the head in a van - he calls for assistance, but by the time reinforcements arrive, the victim, the van and the main witness have disappeared. Desperate to prove his sanity, Quinnan pursues the case vigourously, and enlists the help of DC Paul Riley's brother Joe, who asks the wrong people the wrong questions. PC Polly Page is outraged by a practical joke played by PC Taviner, but she and Quinnan get their revenge in a most amusing way.

DS Vik Singh goes undercover to a 'car cruise', where he becomes involved with a well-organised car ringing gang led by Kevin North. Meanwhile, DC Mickey Webb tries to cultivate an unofficial 15-year old snout named Tyro Shaw, in the hope that he will grass up his father, Steve Shaw. Singh poses as a car thief, and is soon in with the gang, even gaining a meeting with North's boss - Jennifer Salter. As Webb gets frustrated by Shaw's dead-end leads, Singh pushes the boy too far about his involvement with the gang.

Tyro Shaw threatens to blow DS Singh's cover in the car-ringing gang, but is convinced otherwise. Singh seems to have impressed both Kevin North and his boss, Jennifer Salter, who seems quite taken with him. Salter tells Singh the gang is moving on soon, and he realises he must get the evidence in North's office. As Singh enters the office, Webb realises that Tyro Shaw has set them up, and Vik is abducted by North and Salter. Webb convinces Tyro to tell them where Vik was taken, and CID narrowly rescue him from being set alight.

DI Cullen leads a drugs raid on a warehouse owned by his old nemesis, Terry Barlow, but finds nothing. Cullen is furious with DC Glaze, whose snout tipped them off about drugs on the premises. PC Harker and PC Rickman deal with a domestic case involving an argumentative couple, the Carters, and their baby. Neither case makes any progress until a neighbour reports that Barlow has been to visit the Carters on several occasions. Determined to get one up on CID, Harker puts the pieces together and comes up with a theory that the Carters are putting their baby up for sale on the Guatemalan black market with the help of a doctor at St Hugh's, and Barlow is the broker. Despite warnings from Glaze, Harker presses on and is proven correct when they raid a hotel where the exchange has taken place. Baby Sean is recovered, and the police race to an office building where Jackie Carter is threatening to kill herself.

The Section House is closing, and PC Reg Hollis is not only looking for a new place to live, he is also applying for a transfer to SO14 (the Royal Protection unit). He is about to buy a flat owned by an elderly friend, Doreen Tyler, but she changes her mind at the last minute, so he moves in with Tony Stamp temporarily. Hollis's intuition gives CID an important lead on a planned armed robbery, but his uniformed colleagues conspire to have Nick Klein organise the Section House closing party instead of him. Deciding to skip the party, Hollis goes to visit Doreen, but finds her dead in her flat. With no alibi, Hollis is the prime suspect for her murder, and he is suspended from duty. As Stamp and Klein work to find someone who can verify Hollis's whereabouts, CID discover a woman posing as Mrs Tyler's adopted daughter.

A mad gunman is on the loose in Sun Hill. Supt. Chandler takes a personal interest in the case, but when he confides his reasons to a young woman who was threatened by the gunman, he is horrified to find she was a journalist and the story is published in the Sun Hill Gazette. Feeling unappreciated in the job, DCI Meadows considers other options, and attempts to smooth things over with his long-suffering wife, Laura. Meadows teams up with DS McAllister and the two of them strike out on their own, and after a few close calls, arrest their prime suspect - a motor mechanic with a history of firearms offences. As they interview him however, the gunman strikes again...

At the stakeout of the prime suspect, Chandler prevaricates, and Meadows has to act quickly when McAllister is in mortal danger.

After a minor car accident in the High Street, PC Jim Carver breathalyses an elderly man, but takes sympathy on him and allows him to leave in a taxi. The man turns out to be Hugh Alexander, a High Court judge with a renowned pro-police stance, and Carver finds himself suspected of showing bias, particularly when the other man involved in the accident threatens legal action against the Met. At the trial of a man accused of murdering a PC, PC Worrell feels marginalised as a black officer when she is asked to testify and be a character witness for the dead officer. Ch. Insp. Conway meets with Gary Fablon, and discovers that Fablon is addicted to litigation, and the accident was his fault. Carver, meanwhile, has a chance to redeem himself when Conway hears that Alexander may be drink-driving again that night.

A spate of graffiti taggings in Sun Hill sees the police showing zero tolerance to the perpetrators. PC Carver is sympathetic towards an alcoholic teacher at Canley Art College when his classroom and students' work are defaced. Sgt. Boyden asks PC Hagen to move in with him, but she is reluctant, wanting her own space. To her outrage, Boyden moves her belongings to his house as a surprise. Boyden arranges for the council to paint a wall blank to set a trap for the graffitists, catching quite a few in the process. The defacement at the art college turns out to have been committed by the teacher who is jealous that one of his students is sleeping with his ex-girlfriend, life model Moira Sutherland.

PC Roz Clarke has been working double shifts all week, and goes behind Sgt. Ackland's back to get some more overtime from Boyden as she is desperately in debt. PC Taviner promises her some time in the Area Car, much to Reg Hollis's annoyance. Taviner and Clarke interview Warren Debdale, a student who was brutally beaten, but he insists he didn't know the perpetrators. His father suspects the boy's friends are involved, but DC Glaze discovers the father is being blackmailed by a drug smuggling gang. Assigned to watch Warren in the hospital, an exhausted and miserable Roz Clarke has a coffee with a nurse and is horrified to find Warren missing when she returns. With DI Cullen and CID holding back from raiding the gang in case they hurt the boy, Clarke spots Warren's friend Karen on the estate and she admits he is staying at her flat. CID sweep in and arrest the gang, and Clarke is off the hook for the moment, although her flatmate threatens to throw her out unless she pays the rent she o

Clarke helps Taviner track down stolen diggers and crime families while moonlighting in telesales to pay off her debts.

A distraught PC Roz Clarke fails her probation exams, and goes AWOL instead of returning to the station. A gang of thieves on rollerblades are rampant in Sun Hill, and their mobility makes it very difficult for the police to catch them. PC Taviner arrests a girl, Jackie Burns, at a skate park, but she insists she was just watching the skaters. As the skate gang gets more violent, animosity between PC Worrell and Clarke also grows more fierce, and the two come to blows in the corridor. A tearful Clarke admits her debt problem to Taviner. Scrutinising CCTV footage reveals Jackie's involvment with the gang - she phones them when a potential victim withdraws money from an ATM. Clarke returns home to find the bad news that her telesales commission has fallen through and her flatmate Caitlin wants her out.

PC Roz Clarke unsuccessfully applies for a police loan. PC Des Taviner buys her a pushbike and suggests she sell her scooter, but Roz is far from impressed. PCs Carver and Rickman find a young boy, Gavin Billson, overdosed on drugs, and CID investigate some of the local dealers. When it turns out Gavin overdosed on diamorphine, and after several dead ends, suspiscion falls on Dr Stuart Bremnar, a doctor at St Hugh's, who is also the boyfriend of Roz Clarke's friend Ruth. A review of the hospital's CCTV footage reveals Ruth herself sneaking into a storeroom, and Roz is forced to arrest her best friend.

PC Ben Hayward breaks down when telling primary school pupils about the death of his sister during an anti-drugs talk. Sgt. Gilmore is not happy, but the teacher thinks Hayward's sensitivity will help the students get the message, and may also help them trust Hayward enough to report a bully. An old friend of his sister's works at the school, and she asks him out, although when he meets her at a gallery opening, Hayward thinks her friends are dealing drugs. PC Klein and Hayward find the bully, who goes by the nickname ""Red"", and has been using two fierce dogs to steal money and mobile phones from schoolkids. They trace the dogs to the flat of drug-addicted prostitute Stacy Dodds, and a subsequent search of her flat uncovers a large stash of heroin. Stacy insists her pimp forced her to deal drugs and have sex with Red, and instead of having the dogs picked up, Hayward and Klein search the pimp's boat, finding more heroin. The pair argue: Klein wants to set up an obbo to catch the pimp r

PC Hayward and PC Klein arrange to get their stories straight over the missing bag of heroin. Roz Clarke ends up sleeping with 'Phil the Pill', and is surprised when he turns up at Sun Hill the next day as DC Phil Raven from the Drug Squad. Raven and CID arrest Benji Pullinger for intent to supply, but inevitably the missing bag is mentioned in the interview. Station gossip starts to point towards Klein, and Hayward confesses to Sgt. Gilmore what really happened. While out at a nightclub with his new girlfriend, Fiona, Hayward is sure he sees DC Raven selling drugs, and discovers that Raven and Fiona are previous acquaintences. With Klein's help, Hayward tries to set up a sting to catch Raven - he offers to sell him the missing heroin. They meet in a car park, and Hayward (carrying a bag full of baking soda) is surprised when the tables are turned and Raven arrests him.

Klein's doubts about an unstable Hayward seem to be justified when his friend puts his life in the hands of Raven - an undercover cop with unconventional methods...

Supt. Chandler assigns DC Kate Spears to a project involving CCTV cameras in the Sun Hill area. Much to Sgt Ackland's annoyance, she takes PC Jim Carver with her, and they have words. Spears tells Ackland to take it up with Chandler. But word is getting around that Spears gets special treatment from the boss. When a number of cameras are damaged, two youths who have threatened one of the operators, Pat Spencer, are suspected, but the culprit turns out to be Robert Slade, who the youths call ""weird"". Then Spears discovers Robert lives in community care and thinks the cameras are spying on him. Robert spends a lot of his time in an internet café and tells Hollis about his homepage, where Hollis sees a picture Robert has taken of a shopping centre security guard, Tony Malone. He is being given an envelope by known robber Roger Franklin, who has just finished doing time. Cullen assigns DS Singh and Kate Spears to find out how all these disparate players are involved. Then Pat Spencer is at

While on foot patrol on the Jasmine Allen estate, PC Jim Carver contends with an elderly man, Ronnie Atkins, who wants to deal with the local youths ""his way"". When Atkins' best friend, Len Harrap, is found having fallen from the top of the building, Carver suspects foul play and investigates further. Harrap's GP tells him that Len was recently suffering from Post-Traumatic Stress Disorder, and that he had served with British forces during the Korean War. When a man matching the description of the association secretary, Charles Barratt, is reported to have left Len's flat, Atkins realises what has happened. Barratt was a corporal in their platoon during the war, and had forced Len at gunpoint to murder surrendered Chinese soldiers. When Len's daughter put his name up for the reunion, Barratt realised this was his chance to get rid of the photographic evidence of his war crime. Carver admits it will be difficult to get the CPS to prosecute Barratt, especially now the photographs are mis

When an undercover officer from the Met's Football Intelligence Unit (FIU) is found stabbed after a football game, Supt. Chandler and Ch. Insp. Morys from FIU send a Sun Hill team to infiltrate Britannia, the hooligan gang responsible, and investigate their leader, a former police sergeant named Julian ""The Nap"" Napper. DC Mickey Webb goes undercover as builder Mickey Malone with support from DS McAllister as his girlfriend and DC Riley and PC Quinnan as his workmates. Webb successfully makes contact with gang member Gary Hughes, and meets Napper when the gang travel 'up north' for a game.

DC Mickey Webb is close to infiltrating the Britannia gang, despite the suspiscions of some of its members - suspiscions which fire up when DS Debbie McAllister, posing as his girlfriend, turns up to a gang meeting overdressed and wearing Givenchy perfume. Julian Napper smells a rat and follows McAllister as she desperately tries to find a hospital to keep her cover as a nurse intact. Napper catches up with her and accuses her of being an undercover reporter - with her cover blown, McAllister returns to Sun Hill. Supt. Chandler blasts her for her stupidity, and forces her to take notes as they hear Webb taking a severe beating from Napper's thugs over his mobile phone. As DCI Meadows races to save Webb, Napper stops the beating and welcomes ""Mickey Malone"" as a full-fledged member of Britannia.

A series of dawn raids captures most of the Britannia gang, but Julian Napper and Gary Hughes are still at large. With Napper on the loose, Supt. Chandler and DCI Meadows insist DC Webb go into hiding, but he refuses to be intimidated, even when DC Lennox's wife's car goes up in flames. Webb convinces Gary Hughes to tell him where ""The Nap"" is, but Napper still manages to stay one step ahead of the police every time. Chander and Ch. Insp. Morys begin to suspect that Webb is the one informing Napper of their movements, but DC Riley and PC Quinnan's investigations turn up the FIU's DS John Curtis as Napper's brother-in-law and the informant. Webb races to Napper's hideout, but is too late to save Hughes from being stabbed by Napper.
