In this German horror flick about medical students, Gretchen is the hot schnitzel who bails on a relationship with Hein, an unstable male character, which is clearly not a good idea. One night, Gretchen and her new beau show up at the morgue for some sexy-time only to be greeted by Hein. He kills the guy, then fatally poisons Gretchen, and leaves her dead body there—it's the morgue, after all. Like any smart killer, he decapitates her and takes the head with him.
