Baron Frankenstein is dead. Or at least, that's what he wants the public to believe. To carry on his work, he holes up in a place where the possibilities are utterly maddening: a home for the criminally insane. A hand here. A brain there. True to form, the Baron (Peter Cushing) keeps his gruesome creation (David Prowse - widely known for his later portrayals of Darth Vader) in stitches in this sixth and final fright-fest in Hammer Films' Frankenstein cycle.
