It’s opening day of the bluefin tuna season, and the first fish can bring big money. With a payday at stake, every captain is fighting to land a tuna.

As a massive storm front slams the fishing grounds, the fleet takes big risks to catch the elusive bluefin.

As the season reaches a turning point, a change in the quota forces boats to push their limits, creating tension on the water.

It's week six, and Pin Wheel has a narrow lead over last season's champion fishing vessel Tuna.com, while Hot Tuna, Hard Merchandise and Kelly Ann are lagging behind. Now, Captain Paul Cheney and his crew are about to enter the scene and shake things up, with the smallest boat in the fleet — the fishing vessel Drama. They have a lot of catching up to do, with six weeks of the fishing season gone and no tuna. Meanwhile, the crew of the FV-Tuna.com will have to start their trip without a captain, and Dave Marciano gets frustrated as Hard Merchandise keeps hooking and losing bluefin. With each vessel struggling to put meat on the deck, anyone could end up on top this week.

Just one or two fish is all that separates the top four boats as the crews enter the final five days before the Atlantic bluefin tuna season in Gloucester, Massachusetts closes and the competition comes down to the very last day as the boats scramble to land more fish.
