Capt. Stubing announces that his nephew, Courtney (Peter Isacksen), will be joining the cruise. The captain tells purser Gopher Smith, Doc Bricker, cruise director Julie McCoy and bartender Isaac that Courtney is "a typical Stubing," that he will soon enter Annapolis and that the crew is under orders to work with the young man, who turns out to be a gangly klutz in need of help. "The Last of the Stubings" was written by Michael Norell. In "The Million Dollar Man," written by Steve Pritzker, embezzler Bill Thompson (Frank Converse) is strongly attracted to the lovely Stephanie Lewis (Marcia Strassman) from the moment he first spots her. Stephanie is equally interested in Bill because she's an undercover cop assigned to the case. Noreen Badger (Pat Crowley), an attractive spinster, and her widowed sister Rose (Marion Ross) had planned a nice, quiet visit at sea in "The Sisters." When Noreen becomes involved with passenger Clark Tyler (Brett Halsey), Rose resents it. Ray Jessel wrote the script. All episodes were directed by Jack Arnold.
