PC Luke Ashton and PC Dale Smith chase a stabbing suspect onto an estate, but are separated and Ashton is paralysed with fear when confronted by the knife-wielding youth.

After Forbes uncovers a condom in the victim's room, Proctor is infuriated that he has corrupted the evidence. As Forbes is implicated by a security guard who spotted his car at the time of the attack, Proctor and Acton arrest him, and a besotted Proctor ignores Forbes protesting that Acton planted a screwdriver with paint at the scene.

Calder admits while he is on the verge of promotion to Superintendent, an armed robbery that went wrong has left him under the kosh. With a suspect vanishing right before the job, Calder claims CIB are investigating a theory that one of the Barton Street CID team tipped the gang off, but Meadows is skeptical and leaves Calder to it. Coincidentally, Calder's elusive suspect is found as the victim of a beating attended by Garfield and Stamp, with a member of the public attempting to help savagely assaulted as a result.

New PC Nick Klein is friends with the organiser, Anil Indrani, but the brother of Klein's girlfriend Pam is arrested by PC Dale Smith as he rushes to fight off the attackers. Paired with Smithy the next day, Klein manages to defuse a tense situation when Smith confronts a group of black youths at the market. That night, Indrani's club is raided by officers from Barton Street, led by DS Vickers. Klein is certain that Vickers team has planted drugs on the Billy the DJ, and begins to suspect they were also responsible for the attack on Indrani. PC Smith is in trouble: the youths at the market were undercover police officers conducting an 'integrity test' and Smithy's attitude to racial matters leaves a lot to be desired. As Klein lights up a joint at Pam's house, DS Vickers raids the place and threatens to arrest him for possession unless he helps him destroy Indrani.

With DS Vickers blackmailing him over his use of cannabis, Klein is more determined than ever to bring the corrupt officer down. Brownlow asks Worrell to join the case, but she accuses him of going after her skin colour, rather than her ability to do the job, and turns it down; instead, the role goes to Rickman. She is tasked with going undercover as Sally Holland, with her cover being an ex-girlfriend of Anil Indrani in order to lure Vickers into planting drugs on Indrani. Vickers calls on Smith to help him with an unauthorised OBBO, and when he recognises Rickman, he blows her cover. Klein confronts Vickers as a last resort, but he is devastated to discover that Vickers has arranged for Area Drugs to bust Indrani, and he is arrested along with Klein's girlfriend Pam. Klein is furious to discover that it was Smith who blew their undercover op, and presents him with all the evidence he has on Vickers in an attempt to open his eyes to what his friend is really like.

Rawton is furious when Meadows pulls her OBBO on convicted rapist David Trigg, due to budgetary reasons. She is quickly put on a series of robberies, then onto the case of a missing teenager. She is determined to prove Trigg could be involved due to the proximity of his home to the missing girl. However, Trigg comes forward as a witness and gives a description of a man that the missing girl's friend identifies as Paul Myers, who is brought in due to a suspicious bruise on his knuckles. The girl is later found as the victim of a serious assault, but Trigg's relationship with a local suddenly returns him to the top of the list of suspects, but the biggest shock is that he has abducted a woman he wrote to whilst in prison. As the ramifications of Trigg's actions come to light in the fallout, Rawton clashes with Meadows about financial planning taking priority over people's safety.

Someone has been injecting mercury into oranges as a protest against GM foods. Security footage shows a 'New Age' couple lurking around the fruit section, but when they are questioned, it appears they were stealing oranges rather than contaminating them. Supermarket shelf stacker Darren matches the description of the perpetrator, and when challenged, he incapacitates DC Proctor and takes him hostage. Locating his flat, the police find Proctor alive and well, but then word comes through that Darren is in the children's ward at St Hugh's armed with a gas grenade. SO19 arrive at the hospital, but DS Stanton manages to talk Darren into giving himself up.

Unknown to him, PC Dave Quinnan is also trying to contact Jenny. Both are distracted, but Quinnan nearly blows an obbo to catch a disqualified driver when he tries to call again.

Brownlow scrambles into damage control with more regard for the Met's public image than for the welfare of his officers.
