 In 1902, John (Scott), his much younger wife Maida (Scott's real-life wife, Trish Van Devere) and their infant son David (played by both Lee Montgomery and John David Carson) are the only survivors of a ship that crashes into the rocky beach of an uncharted island during a violent storm.By 1912, David, now a seemingly happy 12-year-old boy, begins to enter puberty.By the time he is 17, David is consumed by lust for his mother, which drives a wedge between him and his father to the point where they hunt each other down for the affections of the only woman on the island.
