An obsessive scientist is determined to create life, and builds a creature using parts taken from various corpses. He succeeds in animating the monster, but its brain is damaged in the process, driving it mad and causing it to embark on a killing spree. The first in Hammer's series of horror films inspired by Mary Shelley's novel, starring Peter Cushing and Christopher Lee.

Baron Victor Frankenstein has discovered life's secret and unleashed a blood-curdling chain of events resulting from his creation: a cursed creature with a horrid face — and a tendency to kill.
