The Nostril Picker.

Joe is an ugly loser, incapable of picking up women. But when he’s taught a magical power, capable of transforming him into anyone he pleases and then back to his normal self, he decides to use it to live out his perverse fantasies. Initially content just watching them shower, Joe soon tires of mindless nudity and gears up to take his ultimate revenge against womankind: luring them to his shabby apartment, violently killing, and even eating them!
