The Rhinos are a group of happy-go-lucky lodge brothers out for a good time during their annual convention and have chosen Merrill Stubing (
Gavin MacLeod) as their honorary Rhino of the Year. Their head, Marv Mason (
Mike Douglas), asks Merrill to choose a crew member to say a few words at the award ceremony. But when Merrill chooses Isaac (
Ted Lange), the Rhinos reveal themselves as bigots. Barry and Toni Cooper (
Kevin McCarthy and
Stella Stevens) were married for seventeen years, apart for four months, and are now taking one last cruise before they divorce - unless the romance of an ocean cruise changes their plans. Russ Butler (
Paul Kreppel) is traveling with his newly divorced buddy Wally Denton (
Paul Sand), who takes a liking to fellow passenger Sally Thorner (
Donna Pescow), without knowing that she is a professional sexual surrogate, whom Russ hired to cheer him up.
