In their 10th season as competitors, the Gloucester captains face an unprecedented challenge: making a living in a bluefin market that's struggling to rebound. The resilient fleet decides to work together OBX-style to help each other catch. The five original boats are joined by a familiar mix of recent captains and a tuna legend, whose skills immediately puts the entire fleet on notice.

Teaming up with Wounded Warrior Project, Dave Marciano recruits five other captains to put competition aside for a new mission: to bring a veteran on board for the ultimate fishing trip. The fleet gets to know about their guest angler's proud service in the armed forces, and how events like fishing help in readjusting to civilian life. Each veteran becomes a part of the crew and experiences the thrill of fighting a fish.

In a tough season where all the captains have agreed to work together, Dave Marciano defies the others by fishing in a secret location on his own. His ploy proves to be successful, as the Hard Merchandise catches tuna and stays on top of the leaderboard. But once the truth comes out, Marciano's sneaky move alienates him from the rest of the fleet and could cost him in the long run.
