All is luxurious and voluptuous aboard this millionaire Merrymakers yacht as it cruises the Mediterranean Sea. The fun and frolicking aboard is only surpassed by the foursomes extensive urge for lascivious pleasures. Sex and intrigue lurk on board ship when a beautiful and conniving woman joins the party for what appears to be sheer sexual enjoyment. She has her way with the millionaires, steals their jewelry, and escapes. The escapades that follow, abound with truth and honesty, and the audacious eroticism of the French.
