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.

At the midpoint of their season, the Odyssey Marine crew are on the hunt for a ship code-named "Malta", a 19th-century paddle wheeler with potentially a $32.5-million cargo.

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."
