Plot

A group of friends play volleyball on a beach in Venice, California. Jackie, one of the group, is a high school senior throwing a slumber party that night, as her parents are out of town looking for a new house. When the friends leave the beach, one of the girls, Sarah, gets into her car and is brutally murdered by an unseen assailant, (The Beach Weirdo), in the backseat with a power drill. Jackie returns to her home, and finds her odd neighbor, Morgan, there, wanting to tour the inside of the house; he tells Jackie he is considering purchasing the property when she and her family move.
