Park Plaza Mall has just installed a state-of-the-art security system, including shutters across all exits and three high-tech robots programmed to disable and apprehend thieves using tasers and tranquilizer guns. Four couples: Rick and Linda, Greg and Suzie, Mike and Leslie, Ferdy and Allison, decide to have a party in one of the furniture stores where three of them work. After hours, all of them (except Allison and Ferdy) begin to have sex, drink, and party inside the furniture store.
