The Night Before (1988) on Netflix

Plot summary

Winston Connelly, a nerd, wakes in an alley in a white tuxedo jacket with no memory of the night. He had been going to the prom with Tara Mitchell, the popular head cheerleader, who asked him after losing a bet on a football game. Her father, a police officer, warned him to have her home by midnight. Winston recalls getting lost in East Los Angeles, where a man reached through his car window and stole his wallet. A parking stub in his pocket leads him back to a car taken by a stranger named Danny Boy, and to a bar where the hooker Rhonda greets him familiarly. Tara is missing and a pimp named Tito wants him dead.
