Virginal nerd Jon Pigeon, manages to secure a job in a sex research institute where the patients run about the corridors naked, nude aerobics are encouraged and no man is safe from the crotch-grabbing tea lady. In his attempts to seduce pretty office secretary Cheryl, Pigeon invents a machine called Agnes that emits a 'sonic aphrodisiac' guaranteed to turn any man or woman into an slathering sex maniac. Although his attempts to zap Cheryl are singularly unsuccessful, Pigeon gets some interesting results when he accidentally turns the 'sex ray' on his bullying boss Nutbrown and the prudish Mary Watchtower.
