Plot summary

This film tells several intertwining stories of the patrons and staff of a fictional Los Angeles disco club 'The Zoo' on one long Friday night. The central characters include:Tony Di Marco (Jeff Goldblum) is the owner of The Zoo. Lecherous and promiscuous, he's inordinately fond of his expensive sports car.Bobby Speed (Ray Vitte) is the club's disk jockey who's broadcasting his first live show from the club.Frannie (Valerie Landsburg) and Jeannie (Terri Nunn) are two high school friends who want to win The Zoo's dance contest to buy KISS concert tickets for themselves.Carl (Paul Jabara) and Ken (John Friedrich) are two best friends who frequent the The Zoo. Carl is a hopelessly near-sighted shlub looking for a casual liaison, while Ken is just looking for a girlfriend.Dave (Mark Lonow) and Sue (Andrea Howard) are a young married couple celebrating their fifth wedding anniversary.Jackie (Marya Small) is another woman who frequents The Zoo. She is a dental hygienist by day, and a pink-haired, a drugged-out disco freak by night.Jennifer (Debra Winger) is the klutzy new girl in town who is taken to the disco by her know-it-all friend Maddy (Robin Menken) who's not as sophisticated as she thinks she is.Nicole Sims (Donna Summer) is an aspiring disco singer hoping to make her debut at the Zoo.Marv Gomez (Chick Vennera) is a self-described "leatherman" who lives to dance.Malcolm Floyd (DeWayne Jessie) is the roadie for The Commodores (appearing as themselves), responsible for delivering their instruments to the club by midnight for their appearance.Gus (Chuck Sacci) and Shirley (Hilary Beane) are a mismatched couple on a blind date.Sue insists her uptight accountant husband Dave take her to the disco after having dinner at a local restaurant despite the fact that it is already 10 PM. On a bet with Bobby, Tony tries to pick up Sue when she and Dave walk into the club. Dejected that some other man is flirting with his wife, Dave ends up drugged and renamed "Babbakazoo" by Jackie, and makes a fool of himself.Carl and Ken are repeatedly thwarted in their attempts to meet girls on the dance floor and the bar.Meanwhile, Frannie and Jeannie trick Marv into helping them sneak into the disco after several failed attempts at gaining entry.Elsewhere, Jennifer tries to meet a guy, but Maddy vetoes each of the guys Jennifer is attracted to.Nicole repeatedly attempts to slip into the DJ booth to get Bobby to play her single.Crude garbage collector Gus is horrified that the dating service has matched him with a prim college educated woman, and one who is taller than he is.Floyd gets stopped repeatedly by the police on suspicion of stealing The Commodores' instruments.Back at the club, Marv teaches the uptight Ken how to dance in the parking lot.Maddy ends up ditching Jennifer to attend a hot tub party (with the same sleazy guys who came on to Jennifer).Gus and Shirley decide to give it a try. They leave the disco together.Carl finally meets a girl at the bar, but gets locked in the stairwell before they can leave together.Meanwhile, Floyd finally makes it to the club in time for the Commodores to play but before they go on, Nicole sneaks up on stage and scores a huge triumph singing "Last Dance".Frannie, after tricking Marv's dance partner (Nanci Hammond) into the locked stairwell, enters the dance contest with Marv. Carl and Marv's dance partner end up hooking up in the stairwell.Jennifer and Ken share a romantic dance, as do Nicole and Bobby.Dave finally comes down from his "acid trip" and Sue ditches Tony to return to her husband. As Tony prepares to leave for the night, his parked car, having taken innumerable hits from pretty much every other character's car, falls apart in the parking lot.At the climax, Marv and Frannie win the big dance contest. Deciding that the KISS concert is "kid stuff," Frannie and Jeannie, now self-proclaimed "disco queens," go with Marv to hit another disco for the 1:00 AM dance contest.
