Still hot on the trail of a millionaire, Mike (Merry Anders) sets out on a cruise on the Stella Nassau to the Caribbean. Accompanied to her cabin by Loco (Barbara Eden) and Greta (Lori Nelson) they find cramped Marx Brothers-esque quarters leaving Mike to quip, "this is either the largest closet or smallest cabin in the world." Loco and Greta accidentally miss the final call to disembark as guests and wind up sailing with Mike. They scheme to pull it off by only going out of the cabin one at a time wearing the same hat and glasses. The steward (Paul Dubov) and waiter delivering for three (Benny Rubin, "The Jack Benny Program") puts things together pretty quickly. Loco and Greta are sent to the boiler room to do the ship's laundry, but Loco has met Mr. Prentiss (Peter Walker) and they once again juggle things around in hopes of catching the big one.
