The fleet of crab-fishing boats – and their unforgettable captains and crews – returns for a fourth season of life-or-death adventures on the high seas. Follow the now legendary captains and crews of five crab-fishing vessels on the Bering Sea doing one of the deadliest – and most lucrative – jobs in the world.

Returning this year are the men of the Northwestern, led by Captain Sig Hansen; Captain Phil Harris and his crew of the Cornelia Marie, including sons Jake and Josh; Captain Johnathan Hillstrand and Captain Andy Hillstrand of the Time Bandit; and Captain Keith Colburn of the Wizard, with a crew that includes two greenhorns. New this year are the men of the North American, led by Sten Skaar, and deckhand-turned-skipper Rick Fehst of the Early Dawn.
