Chase and August are at August's gym, where they are volunteering their time to help keep kids off the street and out of gangs. In the boxing ring is Andre, a young fighter determined to stay away from gang violence. But when word comes in that Andre's brother has been shot and killed by a rival gang, Andre swears to avenge his brother's death. Chase and August try to persuade him to let the police handle it, but Andre slips from their grasp in pursuit of the killer. The incident also brings back memories for Chase, who is struggling with unresolved guilt over his former partner's murder by a gang youth.

Art thief Richard Turpin, known as the Gentlemen Bandit, crawls through the skylight of a Los Angeles museum, only to be caught in the act by Chase and August, who apprehend him and haul him off to jail. The British government decides to extradite Turpin, accusing him of association with a radical faction of the IRA. Scotland Yard detective Wilhemina ""Willy"" Smythe arrives to collect Turpin, but her plans are soon thwarted when a terrorist named Riley shows up, who has plans of his own for the thief.
