This year's bluefin quota is just one fish per day, and tensions run high as the limited quota diminishes. When the outsiders employ sneak attacks in an attempt to steal fish from the veterans, the fight becomes personal for longtime rivals Sam Law of the Kraken and Tyler McLaughlin of the Pinwheel, and every boat's loss is another boat's gain in the race to the top of the leaderboard.

The Gloucester fleet is used to dominating its home turf, but as the newcomers begin to come out of a long dry spell, the competition starts to heat up. Summer weather brings a pack of "googans," or recreational fishermen, to Gloucester waters, and the captains are forced to test out different fishing spots in order to escape the crowds.
