Marilee Shaw's inheritance, the yacht Southern Star, is in default to the bank. To save it from the auction block, she decides to honor a Caribbean cruise planned for two couples. But with no captain available, she's forced to approach Gary Pritchard, a man she once loved but refused to marry. He agrees to skipper the cruise, but only if she comes along as crew. In addition to the danger of succumbing again to Gary's charm and good looks, she has other problems. Trying to sell the yacht, the discovery that her customers are not what they seem, and the appearance of an unexpected visitor make the excursion anything but seaworthy. Will the romantic but rocky voyage rekindle their love or scuttle it forever?
