The film begins with Trevor being tried in court on charges of throwing a brick through Mr. Shahnawaz, a Pakistani man's window. He has also been charged with shoplifting from Harrods. Trevor shows no sign of repentance for his deeds, and is defiant when questioned by the judge. Trevor's social worker, Harry Parker (Eric Richard), believes Trevor can reform, so he has him sent to Hooper Street Residential Assessment Centre, where his punishment will be determined. The deputy superintendent in the assessment centre, Peter Clive (Bill Stewart), admits Trevor, and he is allocated a room with Errol (Terry Richards). Errol tells him about the contract that centre inmates are made to sign, promising to co-operate.
The next day, Trevor leaves the assessment centre, to visit the job centre and procure a job, as instructed by the magistrate. However, Trevor, accompanied by Errol, breaks into a car, and drives to the job centre. Near the job centre, he buys Evo-Stik for huffing, and immediately enters the job centre. Trevor breaks the queue, and demands a job from the job centre attendant. When asked to wait, he storms out, and hurls a brick through the job centre window. He makes his escape, and walks with Errol to an abandoned swimming pool where he has hidden some tools, ostensibly to break into cars. Trevor pockets the tools, and hands a key-bunch to Errol, instructing him to get it into the centre, and hide it. He then breaks into another car, and takes it and drives away. He orders Errol to get out, saying he's visiting some mates.
In the next scene, Trevor is seen eating a sandwich in the car, parked near the assessment centre. Peter Clive arrives riding a motorcycle, and notices Trevor in the car. Trevor chucks the half-eaten sandwich out the window, and walks into the assessment centre. Peter Clive stops him, and tells him to get rid of the car. Trevor refuses to admit that he nicked the car, but agrees to get rid of it.
