TUESDAYS 9PM

An adrenaline-packed new season brings a fresh new face to the Bering Sea. At just 23, Sean Dwyer captains a boat named Brenna A as he fights for the legacy of the father he lost too soon. 

Sean grew up in a fishing family with seasoned sailors for parents - his mother, Jenny, and father, Pat. Tragically, Pat Dwyer was diagnosed with ALS in 2004. Knowing his life would be cut short, he bought the Brenna A as his final project for his son to run after he was gone.

Sean listened closely to his dad in his final years to learn the ins and outs of the business of fishing in Alaska. But, having planned to fish opies, Sean is thrown a curveball when Sig offers  up 200,000lbs of bairdi crabs. Never one to turn down a challenge, Sean accepts.

After a rush to get the boat ready, the Brenna A is plagued by delays due to bad weather, not to mention crew injury. When they finally got out on the ocean, Sean and his crew of “lost boys” must hammer through the weather in the battle to meet their quota deadline.

Will Sean find that crab fishing isn't all it's cracked up to be? And how will the crews of Cape Caution, the Northwestern, and Cornelia Marie fare this season? Don't miss the 12th series of Deadliest Catch, exclusively on Discovery, to find out.
