Kras (Gert Frobe), a relentless police inspector, is tracking a series of mysterious murders that all seem to point to one place: the Nazi-built Hotel Luxor. Each grisly crime has the mark of Dr. Mabuse, a well-known evil genius -- but he's been dead for 30 years. Now, Kras isn't trusting anyone. Director Fritz Lang's final film co-stars Peter van Eyck, Dawn Addams, Wolfgang Preiss and Werner Peters.
