The seniors of Herbert Hoover High School hold a prom they will never forget. Popular girl Shelley ditches her date and ends up spending the night with the more unpopular Dan; Kevin the jock goes out with nerdy Angela because he has heard she is easy; Patrice blames her boyfriend Roger for everything that doesn't go the way she wants it to.

Valerie's husband Darryl leaves for work as usual, but never returns. She hires private eye Shepard to find him. Soon he discovers that David had a second identity and obviously doesn't want to be found. But since Shepard is strongly attracted to the pretty Valerie, he investigates further and gets involved more than professionally.
