Spears and Worrell chase a suspect from the scene of a violent assault. They discover that the victim, Donna Elliot, is the sister of Frank and Peter Elliot, two insurance brokers suspected of being the ringleaders of a post-match fight that has been arranged between two rival gangs of football fans. With Sun Hill as the venue, Chandler assigns Cullen to the case, but Meadows is determined to show him up by cracking the case himself using a teenage assault suspect and member of the Larkmead Crew as an informant. When Cullen and Lennox discover Meadows' informant has lied to him about the gang's intentions, CID and uniform rush to head off the mob before they attack an Asian marketplace.
