The Zoo is the hottest disco in town, and on the night of the big dance contest, a wild assortment of disparate characters find themselves out on the floor together. DJ Bobby Speed (Ray Vitte) is convinced that broadcasting the show live on the radio waves and having the Commodores as musical entertainment will boost his career, but when their equipment gets lost on the highway, he starts to lose his cool. Nicole (Donna Summer) is a bumbling but beautiful neophyte singer who schemes to earn her big break on the disco's stage. Frannie and Jeannie (Valerie Landsberg and Terri Nunn) are underage high school girls who need the contest prize money to buy Kiss concert tickets. A bored married couple (Mark Lonow and Andrea Howard) stumble into the Zoo on their anniversary; their relationship is tested by a wacky pill-popping vixen (Marya Small) and the disco's womanizing owner (Jeff Goldblum). A host of mismatched singles make the scene hoping for a chance at love (or at least a one night stand), though the exuberant Marv "Leather Man" Gomez (Chick Vennera) lives only to dance, and expounds on his philosophy at length. There's plenty of thumping disco action and nothing but happy endings in this colorful period comedy.
