After a disappointing North Atlantic bluefin tuna season, Captain Dave Marciano of the Hard Merchandise and Captain TJ Ott of the Hot Tuna travel south full steam into the waters of the Outer Banks, N.C., to extend their season and salvage their losses. In the South, the competition is fiercer and the stakes are higher than ever before.

The Southern captains fear a full-scale Yankee invasion of their waters when another Northern boat ' the Pin Wheel with Captain Tyler McLaughlin ' comes steaming into the Outer Banks. This trip, McLaughlin is desperate to make up for the embarrassing last-place finish he landed last season, and to help him he adds Paul Hebert onboard as co-captain.

With six of the finest tuna fisherman traversing the Outer Banks in the hunt for bluefin, competition gets super competitive. The strict bluefin quota is rapidly starting to fill, and time is of the essence for all the captains. Dave Marciano has been unable to land a single catch and fears the huge gamble he made in traveling south will not pay off.

Weather in the Outer Banks takes a turn for the worse, pitting man against sea as the turbulent Atlantic Ocean threatens the fishermen's quest for bluefin tuna. With ominous weather looming and the bluefin quota quickly filling, the pressure is on for the Northern and Southern boats to act fast or risk financial ' or nautical ' disaster.

Winter releases its fury on the Northern and Southern boats as a dangerous storm makes its way through the Outer Banks, giving the fishermen their toughest battle yet, facing high winds, snow and boat-crushing ice. The strain gets heavier for each fisherman as the ongoing hazardous weather obstructs their hunt for bluefin tuna.

Local rivals Fishin' Frenzy and Wahoo strive to out-fish one another and become the top-earning boat of the fleet. Meanwhile, Southern captain Britton Shackelford and his first mate Caine are struggling to make ends meet with only one catch so far.
