The Odyssey Explorer crew sets its sights on a German U-Boat which still carries its deadly load, a World War I tanker carrying beef, and a suprisingly lucrative ingot-laden wreck.

Odyssey has found one of the most famous U-Boats in history, the U103. The crew also takes a WW2 veteran back to the scene where he recounts helping rescue survivors from the now sunken convoy ship Cyrus H. McCormack.

The Odyssey Explorer crew turns its sights on cargo that can easily be turned to coin. A modern container wreck spews hundreds of sealed champagne bottles across the sea floor. Could this be a lost shipment of rare and valuable wine?

Odyssey's season is winding down and winter weather is winding up. This may be their last chance to lay claim to a 20th-century steel-hulled ship with cargo that could be worth more than $100 million.

The first season finale finds the crew embroiled in a legal battle Spain, over the cargo of gold and silver coins found on the wreck they call the "Black Swan."
