Monstrosity, or The Atomic Brain, as it was called on television, is one of the fifty classic science fiction movies that I have on twelve DVDs. The movie is an updated version of Frankenstein. Hetty March is a wealthy widow devoid of conscience. Her husband had died and she's taken Victor as a lover, whom she'd later later killed. Mrs. March has hired a mad scientist named Otto Frank to transplant her brain into a young body. However, his experiments with dead bodies aren't successful, and he needs to have fresh, live bodies for his experiments. Mrs. March lures three young women to her house under cover of darkness because she doesn't want people to see what's going on. She then succeeds in killing all but one of them, who escapes before the house explodes pursued by Mrs. March, whose brain was transplanted into Xerxes the Cat.
