Fire Island in early May, after the winter ice melts and before the summer crowd arrives, is the ideal time to raise a submarine from the dead. Six adventurers - five men and a woman - salvage a World War I German submarine from the bottom of the Atlantic Ocean. They will use it in executing a daring idea, an idea methodically planned and timed with scientific precision. Their goal seems fantastic, but if they can bring it off each one of them will be rich for life. Only the factor of human relations is not taken into account, and the tension between these six people begins to mount unbearably as the moment looms closer and closer for an Assault on a Queen.
