S3, E9: A young woman is murdered after she identifies an escaped murderer aboard the luxury liner, Southern Queen. Bosley and the Angels are assigned to infiltrate the ship and discover the ring that's helping criminals to escape the country. Sabrina, as the niece of a well known mobster, contacts Leo, a steward of the ship. She pretends to be in trouble and, for a great deal of money, he agrees to take her aboard and out of the country. Waiting aboard to welcome Sabrina is the Liner's new Activities Director, Kelly. Also aboard are a handsome Purser, Ben, a wisecracking doctor, "Doc" and the ship's grumpy Captain, Burner. Kris is also a passenger. She comes aboard flamboyantly dressed and is later joined by bachelor/sportsman, Bosley. There is also a widow aboard, Joan. Bosley falls for her. Kelly is given a note by Ben. Sue's instructed to come to the boiler room at night where she'll be given the name of the leader of the ring. Kelly, trapped in the boiler room by a ring of fire has to be rescued by Kris and Bosley. Sabrina is also told she can see the big boss - this time, by the ship's steward, Leo. Later, he and Ben push her into the swimming pool. Their effort to drown her is thwarted by Bosley and the other Angels. The mastermind is arrested and they sail happily away into the sunset.
