Emma witnesses Beth kill her brother, and the police suspect it was really Emma. John Trevor comes to the rescue when Beth is trying to strangle Emma to death and leaves her with a gun. She suspects that her father was to blame and murders both her parents. When the police arrive, Emma threatens "John Trevor", who now claims to be a paramedic, with the gun he gave her. As she points the gun at Trevor, she is really pointing the gun at herself, and when she pulls the trigger, she kills herself.
