When a botany professor marries a widow with three children, the entire family takes a madcap honeymoon vacation to the Grand Canyon. This doesn't sit too well with the instructor's scheming ex, who plots to win back the heart of her old flame. But when she meets up with the happy groom and his new clan at their destination, the stage is set for some Arizona awkwardness. Fred MacMurray, Claudette Colbert, Rita Johnson star. Standard; Soundtrack: English Dolby Digital mono.
