New PC Cathy Bradford makes an immediate impression after overpowering a thug who escapes Gilmore's clutches in custody. Bradford becomes the centre of attention as Stamp vies for her affections, leading to a series of bets and wise cracking from the relief. Paired on the beat with Hollis, he and Bradford investigate a series of thefts from homes. Meanwhile, Quinnan is seconded to investigate a series of vandalism cases that involve a local daycentre, and Bradford immediately derails Quinnan's progress when she and Hollis interrogate one of the girls who attend the centre. Quinnan gets even when he finds out the culprit is someone neither he or Bradford suspected.

Part 1: Bradford starts an operation at her local gym when the owner, Barry Hunt, reports a series of thefts. Bradford enlists the help of Carver, who uncovers a link to possible steroid use.

Stamp is also asked to go undercover as an HGV driver in the same operation.

Page and Quinnan pose as a married couple running a hotel, while Carver and Hollis, and immigration agent Petrit, pose as their employees. Stamp continues his undercover role as an HGV driver for the firm bringing in the illegals, while Webb, Lennox and McAllister maintain surveillance on the hotel. The hotel is busy preparing for its opening night, and when the temporary staff arrive, Quinnan seizes the opportunity to attract Berisha's attention by ringing the agency and complaining about them. Later, Stamp makes a delivery to the hotel – four refugees who are immediately set to work. He then picks up his boss Kerns and drives him to a lorry park, where he finds twenty scared refugees and a decomposing body.

The operation appears to be in jeopardy again when Petrit declares that he is going in search of his missing sister. Following a lead from a girl at a café, he and Carver visit a pool hall, but have no joy with the doorman. Page meets up with Cullen to give him an update, and tells him that she is convinced that they are being set up for extortion by Berisha. Her suspicions are later confirmed when Berisha presents Quinnan with a bill for excess staff. Initially, he refuses to pay, until Berisha starts to strangle him, watched by a helpless Webb and Lennox. A determined Petrit plans to return as a punter to the pool hall where his sister may be, which is identified as a brothel.

Accompanied by Hollis, Petrit manages to locate his sister Nicola, who has been working as a prostitute for Berisha.

While he manages to calm Asian community leaders over the Neo-Nazi march, the night ends in tragedy.

Chaos ensues in custody as the relief try to track down every know player in the race war, with Chandler attempting to rally the troops as they seek to bring Conway's killer to justice. Sandra Conway attends the station and blasts Chandler when he suggests a police funeral, but seeks solace in the arms of Ackland. Webb, Spears and Taviner are told by both parties of the race war that a supremacist was assaulted by a police officer, with Azim Khan commenting that the assailants were two black officers, so they grill Glaze and Singh. With both failing to crack under pressure, Webb breaks the news to Meadows. Singh goes off to grill prime suspect Jeff Simpson, but when his assault of Simpson comes to light, the relief realise they can't nail the man they are certain is the killer.

Taviner and Hollis deal with a number of disturbances involving two local youths, but aren't lucky enough to catch either of them. Monroe organises a fund for Conway, and while Chandler makes a very charitable donation, Taviner is forced to write an IOU. With no way of contributing to the pot, Taviner believes he has hit the big time when he catches up with one of the youths and confiscates £200 from him. Managing to rescue his reputation amongst the relief, he is soon left in deep trouble as unbeknownst to him, the money is fake. Stamp and Page find a number of petrol bombs and fireworks near Simpson's bookshop, but it is Azim Khan who finds himself being arrested for stealing petrol.

A desperate Taviner stands by a critically injured Harker's bed as he fears his role in the bombing being exposed. Page recovers after being found in the fire, but she reveals to Stamp that she tried to take an overdose, having found her depression too much to handle. When Stamp confronts a distraught Ackland, who spends the day seeing the family of the deceased officers, she demands Page go on long-term leave to seek help. Webb is determined to see Spears as she lies critically injured in hospital, but with family the only visitors allowed, he is left devastated when she succumbs to her injuries without him there. His sadness turns to anger and he unleashes fury on Chandler at a press conference. Meanwhile, Glaze struggles to comprehend recent events, telling Lennox he thinks Simpson is involved, feeling guilty at the thought that Singh's attack could've led to the death of Conway and those in the station attack.

Chandler hastily makes Boyden Acting Inspector in the aftermath of the station blaze, immediately taking Gilmore's idea to hold a minute's silence for the victims to boost his credibility within the relief. Taviner considers killing Harker to keep him quiet, but as he decides against it and prepares to confess to Hollis, Harker succumbs to his injuries. Elsewhere, McAllister tries to find "evidence" to ensnare elusive safecracker Peter Grace, whose case file was lost in the fire. Gilmore and Carver uncover a stolen jewelry scam, after a bizarre call about a man digging holes in a two gardens, while Lennox and Glaze are reprimanded by Meadows for their pursuit of Simpson.

As the relief try to get back to normal, Stamp tries to catch a teenager who stole flowers from outside the station, while McAllister tries to track down an internet fraudster. McAllister is knocked back by Meadows as she tries to get on a computer training course, so she flirts with Chandler to get on board through him. Meanwhile, Glaze continues with his vendetta against Jeff Simpson, but it's decorator Harry Fullerton who becomes prime suspect for Devlin and Hayes.

A tough day arrives for the Sun Hill team as they prepare for the funerals of their seven murdered colleagues. Charles Brownlow and Bob Cryer return to attend, and Meadows warns Webb not to show Chandler up at the funeral, but Chandler's comments about Spears cause Webb to storm out in anger. Hayes and Devlin's reputation with the relief takes a further nosedive when they try to question Taviner at the funeral, who is left feeling guilty after being asked to take Josh Worrell for a run in the Area Car, and his guilt leads him to inadvertadly lash out at the young boy. The memorial is an uncomfortable affair with MIT hanging around, but the mood is lifted as Hayes and Devlin make their first arrest. Meanwhile, new DC Eva Sharpe is assigned to watch a drug dealer, only to be double crossed by an informant who allowed the dealer to escape without her seeing.

Sharpe suspects Roy Clarke is responsible, having run a counterfeit cheque operation years earlier, but she and Gilmore discover he has left the country. Attention turns to his ex-wife Chrissie and her new husband, Dean Hendrie, suspecting they may be using Roy's old system to set up on their own. When Dean is caught in bed with Jodie, Chrissie decides to help Sharpe nail her husband. However, Sharpe is skeptical about how keen Chrissie is, given how much she stands to gain if Dean goes to jail. Meanwhile, Ackland reconciles with Carver, but she breaks it off again when Chandler offers her the chance to head up the new CSU. Chandler gives into temptation with McAllister, while Rickman and Klein get high at a club, only to get caught up in a brawl between three clubbers.
