As the final week of tuna fishing begins, the Hard Merchandise, the Bounty Hunter, the Tuna.Com and the Odysea steam out together, each captain vowing to catch the biggest tuna before the season ends.

An intense storm slams into the shores of Massachusetts, and meteorologists are calling for winds up to 20 to 30 knots and 4- to 6-foot-high waves. Most wouldn’t dream of steaming out into conditions like these, but a few are brave enough to dare risk their lives — the fishermen of Gloucester.

Meet Kevin and the Christina, a boat that gets its own real life fish story when it snags an eleven-hundred-pound “monstah” right out of the gate. The story of Kevin’s catch, by far the biggest of the season, is the talk of the town and no one takes it harder than Dave on Tuna.com. Dave puts his boat on overdrive to catch up, while Marciano is forced to sit on the sidelines with a charter tour so he can pay off debts.

After watching the Christina catch the biggest tuna of the season, the uber-competitive Captain Dave of the Tuna.com is obsessed with beating the record, and catching a fish bigger than 1,075 lbs!

A mixture of bad luck and mutiny brews in this tumultuous episode of Wicked Tuna. Tensions erupt on New England’s top tuna boat, Tuna.Com, when Captain Dave and Paul get into a heated confrontation that causes Paul to quit!

With just two weeks left until the end of tuna fishing season, Bounty Hunter gains a new deckhand. Paul, formerly of Tuna.com, joins the crew, and Captain Bill hopes he will help turn the boat's luck around. But tensions flare when Paul tries to teach a few things to First Mate Scott leaving questions about whether the new arrangement will work. On the Hard Merchandise, First Mate Jay struggles to prove to his uncle and Captain that he's worth keeping on next season.

Meet the fleet, as peak season begins and the adrenaline rush of “monstah” hunting hits Gloucester. We enter mid-season, but this is when the money is made and tempers run hot. Each captain loads his boat with three thousand dollars worth of fuel, bait, and ice, and heads off for open water where the blue gold is waiting. But it doesn’t take long for things to sour when there’s cash on the line.

Tuna.com continues its winning streak, catching two fish in one day while the rest of the fleet struggles to even find a spot to fish in between the flocks of “googans”—the weekend recreational boaters who seem to make every bite go wrong. Desperate for a catch, Bill of Bounty Hunter starts doing some sleuthing, trying to crack Dave’s code in search of the secret that will bring him the fish—and the money.

A hard season with little money to show has taken its toll on the crew of the Odysea, leading Captain Ralph to lash out at his first mate Pirate. The more Ralph yells, the more Pirate tunes him out, leading to more mistakes from Pirate.

After going bust on his last trip, Marciano of Hard Merchandise wrestles with the trials of being an absentee father when he comes home empty-handed. Though they'd prefer a paycheck to a three-thousand-dollar loss, his family misses him and shows their love and support while his mind remains on chasing tuna. The next day, he repays their devotion when he comes home with a $10,000 fish.
