The auditioner, Mr. Murray (Roddy McDowall), takes Katie to a remote mansion to shoot the movie. Once there she meets the other man involved in the movie; Dr. Joseph Lewis (Jan Rubes). Katie quickly finds herself in the middle of a dangerous and possibly deadly plan, and needs to find a way out of it.
