An illuminated looser proposes to his best pal, impassioned by boats, to convoy a sailing ship to sell it at a better price, overseas in Miami, while dissimulating to him that he has just stolen it. They make scarce badly prepared; in the storm, the damages follow one another, the reserves of food become exhausted... the friendship too. The conflicts degenerate in the middle of the ocean, where each one assumes to have the right to make its own law. To ensure their survival, they must plan to get rid of the other. In this deadly escalation, who will survive ?
