As the Bristol Bay Sockeye Salmon run comes to an end, Captains battle for the last fish of the year and try to hit their season goals. Capt. Luke struggles to keep the Jimmy Jeff running long enough for him to hit 100,000 pounds.

As the Bristol Bay Salmon season grinds to a close the crews are beginning to feel the fatigue. Captain Luke and the crew come to the rescue of a fellow captain and save him and his crew from a dangerous boat fire.

It's July 4th and Alaska Fish and Game has declared open fishing in Bristol Bay. As Captains scramble for their share of the record Salmon migration, Irishman Tom Walsh finally turns tables on fishing partner Vince and comes out on top.

It's make or break time in Bristol Bay, Alaska and peak of the Salmon season arrives with a vengeance. Things are looking bleak for the crew of the Jimmy Jeff until Captain Luke's risky move of secretly fishing the shoreline pays out in red gold.

The darkest day of Captian Luke's career turns to sunshine with some help from Mother Nature. In the Naknek district to the north, fishing starts strong for the Thunder but after a series of empty nets they set out for new - but risky - territory.

Kicking off the fishing in the Naknek district, the Ferrigno family quickly sets the bar with a monster haul. Also in Naknek, the high-octane Thunder is hot on the Salmon trail, but a freak encounter with another boat causes a terrible reversal of fortune.

High-powered high-liner Taran fires up his boat's dual jet engines to scour the bay and nets a promising first haul in Naknek. In Egegik, Luke and crew are dead in the water as they race to get the broken down boat the Jimmy Jeff back in action.

Every salmon season on Bristol Bay is a war, but this year promises to be legendary. The price is historically high, the stocks of fish are huge and the only thing guaranteed is a battle on the bay.
