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.
