The show centres on Jimmy Reardon (Tracey), one of Vancouver's top organized crime bosses, and Mary Spalding (Scott), the director of the Vancouver Organized Crime Unit (OCU), who has offered Reardon immunity from prosecution in exchange for his role as a police informant. The show also stars Matt Frewer as Ted Altman, the scheming assistant director of the OCU who seeks to replace Spalding, and John Cassini as Ronnie Delmonico, Reardon's business partner and confidant.
