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.

Vic and the Strike Team begin to prepare for the money train takedown, even though Armadillo's greenlight still has them on their toes. After embarrassing the department with the Bob and Marcy case, Dutch is forced to take any action necessary to prove himself in a new homicide, while Vic sets out to stop the abuse of a neighbor by her violent boyfriend, and Danny finally makes a stand against Yassirah.
