A determined and demented scientist named Dr. Ood (Horst Frank) is fascinated by the idea of transplanting the head of a beautiful nun, Irene Sanders (Karin Kernke), onto the perfect body of Stella aka "Lilly" (Christiane Maybach), an exotic dancer. After the crazy experiment, it is only a matter of time until the authorities get involved and start hunting for Ood. Helmut Schmid, Paul Dahlke and Michel Simon co-star.
