In the explosive season finale, the fleet continues to battle extreme weather, monster bluefin and uncertain profits as everyone fights to land the No. 1 spot — and one last tuna. With hours left, it's anyone's opportunity to bring home the winning fish. Will the Gloucester captains be successful on their home turf, or will the "tourists" prove too strong to defeat?

It's opening day of the bluefin season, but the coronavirus pandemic promises to make this year different than any before. With less demand for the product, the captains of Gloucester, Massachusetts, face a series of challenges—time off the water, lower prices from the buyers, and day after day of uncertainty—and resolve to work together to make the most of an unprecedented season.

While the bluefin market may be uncertain, the competition remains steady. With limited days on the water, the captains are determined to start the season off strong. Making waves early on is Captain Dave Marciano aboard the newly renovated Hard Merchandise, who seems to have found his mojo after a few disappointing seasons. But will his luck stick around, or are his glory days behind him?
