Family Plot

Alfred Hitchcock's final film is understated comic fun that mixes suspense with deft humor, thanks to a solid cast. The plot centers on the kidnapping of an heir and a diamond theft by a pair of bad guys led by Karen Black and William Devane. The cops seem befuddled, but that doesn't stop a questionable psychic (Barbara Harris) and her not overly bright boyfriend (Bruce Dern, in a rare good-guy role) from picking up the trail and actually solving the crime. Did she do it with actual psychic powers? That's part of the fun of Harris's enjoyably ditsy performance.
