A group of blackmailed guests gather in a remote mansion, hosted by a daffy butler (Tim Curry), in this campy adaptation of the popular board game. Suspicions flare when their ostensible extortionist, Mr. Boddy, appears--and drops dead in the study. Hidden passageways, double entendres, and creative murder weapons come into play as bodies drop, disappear, and reappear on one dark and stormy night. An all-star cast assume the roles of Professor Plum (Christopher Lloyd), Mrs. White (Madeline Kahn), Miss Scarlet (Lesley Ann Warren), and the rest of the multicolored bunch as the one-liners fly in this jaunty whodunit. It all concludes with three alternate endings that let viewers decide who the real murderer was.
