Frankenstein's daughter, or, She monster of the night

 The grandson of Victor Frankenstein, Oliver (Donald Murphy), is hiding away as a laboratory assistant for the gentle Prof. Morton (Felix Locher). While Dr. Morton pursues a pet project, Dr. Frankenstein secretly works his own experiments on his benefactor's niece, Trudy Morton (Sandra Knight). Although these experiments temporarily disfigure Trudy's face and cause her to wander aimlessly at night, they are only a build-up to Oliver's greater goal of recreating life. With the aid of one of his father's former assistants, Oliver constructs a female monster from the body parts of various murdered people and begins to deal a horrible fate upon any who dare stand in the way of his desires.
