All Night Long: Anyone Would Have Done (2009)

A psychopath follows a young woman to her home - the title of the film goes Anyone Would Have Done, so she was probably randomly chosen off the street.Another woman soon joins them - maybe the first one's sister or just a friend.The torment inflicted is initially relatively mild, with the guy more interested in snapping upskirts shots and slipping into hallucinations where the girls are having a good time charmed by his irresistible presence.This probably explains why the girls have plenty of opportunities to to beat the shit out of him and his unremarkable knife, but don't.
