Following the murder of Terry, the Internal Affairs Division begins an investigation into his death, while Aceveda begins his own. Meanwhile, Dutch and Claudette investigate the shooting of a churro vendor that ends in the Barn's detectives busting up a gang initiation.

As Dutch uncovers a lead to the serial killer, a reporter's questions force Aceveda to explain problems he thought were buried fair in the past, while Vic assists Connie as she tries to quit crack cold-turkey in a desperate attempt to keep her son, leaving the other Strike Team members to investigate a strip-club mugging ring on their own.

While the Strike Team puts the finishing touches on the money train takedown, Vic works with Dutch and Claudette to find a missing child, while David gets an unwanted visit from the Chief and Julien is harassed by some of the other officers after Tomas outs him in front of them.

When a gang execution hits close to home for Claudette, Vic, Tavon, and Dutch work together to find the culprit before anyone else gets hurt. Shane, Lem, and Ronnie are forced to choose between hitting the money train without Vic or letting it go. As Aceveda prepares for the city council election, Danny receives some life-changing news, and the harassment inflicted upon Julien reaches a whole new level.
