DS John Boulton is determined to catch a pair of brutal thieves, and he is certain that local crook Mick Glover is one of them. Ignoring protests from Uniform, who already have Glover under surveillance, Boulton leads a disasterous raid on Glover's flat, which puts PCs Quinnan and Garfield's informant Janie in grave danger. When Quinnan and Garfield find Janie's flat on the Jasmine Allen estate vandalised, Quinnan pursues the suspects, but finds himself seperated from Garfield, who can only watch in horror as his friend is beaten and stabbed by a gang of youths.

With PC Quinnan in a critical condition in St Hugh's Hospital, the police descend on the Jasmine Allen estate, determined to catch those responsible. PC Garfield manages to identify most of the gang, and a young boy, Kevin White, bought in for questioning names them as the 'Sun Hill Massive'. Garfield and DS Boulton come to blows when Boulton denies any responsiblity for the attack on Quinnan. Acting on a tip-off, the police raid Mick Glover's flat again, finding he is responsible for the burgleries, and that his son Ben and Kevin White were the ones who stabbed Quinnan.
