The story takes place in a mysterious underworld of swanky nightclubs where armed criminals listen to Rat Pack music and hold shootouts from a seated position, behind desks. Mickey Holliday is the top enforcer for Vic, the mob boss, who is about to be released from a psychiatric facility. In his absence, Ben London has been running **Vic**'s nightclub while Mickey has been romancing both Rita and Grace Everly, which is doubly dangerous inasmuch as they are sisters and Grace was previously Vic's girl.
