From the liner notes

A man, adrift at sea, washes ashore on an uncharted island. There, he finds a gorgeous young woman, Emmanuelle (Gemser). He falls in love with and pursues this uninhibited beauty. Their tropical paradise accentuates the erotic charge as Emmanuelle experiences one exquisite pleasure after another. Laura Geyser's striking beauty and sensuality immediately established her as the reigning queen of the Emmanuelle films!
