Evicted from home and forced to live in a sorority house, Sabrina Masterson becomes attracted to Mort, who owns the hip bar on the beach, but he's involved with pretty overachiever Rita Summers. Sabrina befriends Rita, planning to break up the romance, but Mort still doesn't respond to Sabrina's advances. As she becomes progressively desperate, Sabrina resorts to increasingly dangerous and violent measures to win him over.
