The team must infiltrate a group of bank robbers led by ""Sonny"" Walker (William Forsythe) who shoots his own wounded. Jake Shaw is sent to infiltrate the robbers, but his loyalty is tested in a way that could compromise the team's case.

Jake and Alex go undercover to crack a group of thieves who stole a multi-million dollar heroin stash from a police lockup. ""Sonny"" Walker's (William Forsythe) girlfriend (Angie Everhart) (see previous episode) seeks to continue his operation and confronts Cortez (Steven Bauer), an imprisoned associate who was Alex's lover before she busted him. Alex is torn between her feelings for Cortez and her team leader, Keller (Grant Show), who also has romantic feelings for her. Oded Fehr joins cast.

Jake is dispatched to infiltrate Quito Real's (Ving Rhames) organization, and Alex to infiltrate the equally notorious organization of Benny Li (Stephen Chang). Quito is looking to expand his organization by teaming with Benny Li (guest star Stephen Chang). Elsewhere, unknown to the team, Carlos Cortez (Steven Bauer) is released from prison and the incarcerated ""Sonny"" Walker (William Forsythe) plots his own return.

Jake is posing as a long-time criminal and Alex as a prison psychiatrist when prison inmates stage a rebellion.
