Plot

A fire started by Harry Thompson destroys the Liguria, a legendary ship of the 19th century, and its treasure of gold and diamonds sinks in the sea. Thompson manages to escape unaware that Albizetti sleeps in the same lifeboat he uses. They manage to arrive at a deserted island, which has also been reached on the opposite shore– by the other survivors of the shipwreck: three children, a woman and three men.
