Kingsley James has been hired to skipper a yacht around the Caribbean for two weeks for a vacationing foursome. He's asked his new lady, Marjorie Masters, to join him on the trip as chef and deckhand. Marjorie, a teacher in upstate New York, turns out to be quite the student as K.J. shows her the ropes around the boat. Moonlight sex on a perfect tropical beach is the climax of their adventure so far - which may be continued.
