In "The Captain and the Lady," Bonnie Franklin appears as Capt. Stubing's infuriatingly sarcastic ex-wife who creates havoc aboard the Pacific Princess when she arrives for a cruise with her present spouse (Robert Symonds), the captain's boss. "One If By Land" stars Jimmie Walker and Brenda Sykes as a couple who have been living together in unwedded bliss, until the young lady decides that matrimony is a "must". To forget her unhitchable man, she escapes aboard the luxury ship where she befriends fun-loving Suzanne Somers, who helps her acquire a new outlook on life. "Centerfold" finds Ms. Meredith Baxter-Birney as a girl who once posed in the nude for a photographer. Now engaged to a political candidate (Shelly Novack), she is horrified to learn that the picture is the centerfold of a current magazine. She sets out to recover all copies aboard ship before her future husband sees the centerfold picture.
