The Virgin Islands serve as a backdrop for the Grand Prix Wine-Tasting Competition, whose winner receives a $25,000 prize. Judge Alan Curtis starts a shipboard fling with Marion Blake, without getting to know her well. Julie's Aunt Sylvia Duvall is on the cruise with her friend, Betsy Boucher. Their scheme is for Betsy to meet the wine competition's sponsor Elliott Banning, marry him, and become a wealthy bride. But their efforts may be in jeopardy due to Sylvia's well-intentioned bumbling. Also among the judges is snobbish judge Vincent Van Durling (thetvdb.com)
