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

The smaller quota of one bluefin tuna per day has changed the dynamic of the fleet, making it difficult to take or maintain a lead. It is imperative captains bring in a catch every single day. It also makes fishing far offshore a gamble because of the travel time and extra fuel costs. But one captain, desperate to salvage his season, decides to take his chances on a trip to Georges Bank.

Captain Tyler McLaughlin feels the pressure to stay ahead of his rival Captain Dave Carraro, but a new boat of friendly faces joins the fleet. The Whistler was formerly the original Pinwheel, and Captain Kevin Granfield is an old friend of McLaughlin's. The two captains vow to help each other find fish and give McLaughlin the edge he needs to take the lead. Mechanical troubles plague the Falcon.
