While John is away one day, his daughter, Susan (Lori Loughlin), and her friend Lisa (Meg Ryan), and two boyfriends use a Ouija board in the attic. The game tells them that Susan is in danger. Growing bored, Susan and the others go out in John's motorboat. Susan's mother Nancy (Tess Harper), who has come to look for her, is surprised to see a drenched Susan silently walk up the stairs. Outside John arrives home to find Susan's friends bringing her lifeless body to shore. Nancy has a nervous breakdown and believing Susan is still alive and will return shortly, refuses to leave, even for Susan's funeral.
