In the late nineteenth century, Mexico and France laid claim to Clipperton Island. In 1908 Mexico places a garrison of men and their families on the island to reinforce their claim.
All goes well until 1914 when, because of the revolution that tears Mexico apart, the garrison is no longer supplied. Scurvy claims many of their lives and in a desperate attempt to save those that are left, the Captain tries to row a boat for help. He perishes along with three men he took with him.
The lone man, left on the island, goes crazy and declares himself king. For twenty-two months he rapes, tortures and murders some of the women and children of the garrison. Finally, two of the women are successful in killing him.
A United States warship, looking for Germans, rescues the survivors and returns them to Mexico and safety.
