During a raging storm, a baby is washed up on shore on an island in Greece and is adopted by the wealthy Stanhopes, who name her Lorelei. Eighteen years later, Lorelei, now a woman, invites her school friends to spend their vacation at her villa. One of her guests, Julie, is insanely jealous of Lorelei. One day Gerald Waldron, a disenchanted society fop, sails by on his yacht, accompanied by his social-climbing friend, Hartley Royce. Seeing Lorelei and her friends swimming, they decide to go ashore. Both Gerald and Hartley fall in love with Lorelei, and Julie rages, finding herself relegated to Hartley. Together Hartley and Julie plot to separate the lovers.
