Teenagers Libby and Kit innocently spend an evening making random prank calls. These calls lead to murderous consequences.
When two teenagers make prank phone calls to strangers, they become the target for terror when they whisper “I Saw What You Did, And I Know Who You Are!” to psychopath Steve Marek who has just murdered his wife. But somebody else knows of the terrible crime that was committed that night, the killer’s desperately amorous neighbor Amy Nelson.
