Ward and June Cleaver have nothing on suburban couple Ray and Carol Peterson (Tom Hanks and Carrie Fisher). Together with their perfect son, Ray and Carol are so clean that they squeak. Thus, when new neighbors Dr. Werner Klopek (Henry Gibson), Uncle Reuben (Brother Theodore), and Hans (Courtney Gains) begin evincing bizarre behavior, Ray is slightly put out. Carol thinks that Ray is getting all worked up over nothing. Ray and his fellow suburbanites endure all sorts of slapstick misadventures in the vain hope of getting “the goods” on the newcomers.
