While Vic continues his search for Corrine and their children, the Strike Team allow more drugs into Farmington through a corrupt connection. But when their latest shipment turns bad, they head to Tijuana to uncover the culprit behind the poisoned cocaine. Meanwhile, Dutch and Claudette try to track down the man responsible for "fire-necklacing" the leaders of two separate gangs.

As Vic gets closer to finding his family, the Strike Team focus their attention to Armadillo after he burns down Tio's business, an act that threatens to expose Vic's protection racket. As Claudette gets closer to the truth about Vic's connection to Tio, Dutch is accompanied by the civilian auditor to solve the murder of a meter maid, while Danny and Julien intervene between two feuding neighbors.

Still fuming from the murder of Tio and his brawl with Armadillo, Vic takes a day off to reconnect with his old partner, and soon sets out to help him get revenge against the thug whose complaint forced him into retirement. Meanwhile, an amputated arm sends Dutch and Claudette in search of the sadomasochistic criminal behind the torture and mutilation of a woman who may still be alive, and tensions brew between Danny and Julien after Julien fails to back up Danny's side of the shooting to IAD.

The Barn mobilizes to investigate a massacre at a women's shelter, while Aceveda spends a day on the streets with Julien as the pair attempt to recover a child's stolen bicycle.

With Ronnie's face healed, he comes up with an improved plan to take down the Money Train, and the Strike Team is all in. Unfortunately, a federal criminal comes back to Farmington, and the Team has to use every connection and resource to bring him in before Lanie submits her final report. Meanwhile, Dutch and Claudette investigate the rape of a young girl, and an old friend from the past reappears to make Julien's life hell.
