But George the director tells Bonnie she must stay after hours to rehearse more. Everything dissolves to black. Bonnie now witnesses a real killing with a different Paul, Harry and murderer. Now, the murderer pursues Bonnie, and there is another dissolve to black. Next morning, when the cast and crew arrive, there is no sign of Bonnie.
