Television's most dangerous gold mining is back. The Dakota Boys double down on everything including crew, locations, and equipment, while the remote Alaska conditions punish their efforts like never before.

Equipment failure leaves one crew member with life-threatening burns, while the advantage of having two dredges up and running proves successful.

A hungry and aggressive apex predator tears through the miners' camp, forcing the crew members to come together to find a solution; the crew uses new equipment to speed up their gold recovery.

Fred and Dustin disagree on where to find the gold and dig separate holes. But, a fierce confrontation jeopardises the entire operation.

Finding their biggest gold nugget of the season is a great sign, but soon enough heavy rain means flooding, and, despite the danger, the Dakota Boys still go out and dive.

After being rescued from the water, Dustin is forced to look for a new mine site due to the flood, but he soon finds out that the McKinley site may not be a lost cause after all.

Digging deeper than ever, the crew sees no sign of the promised bedrock gold; just when the crew starts to question Dustin's leadership, his determination pays off.

The Dakota boys are dredging towards a nugget trap they believe holds a jackpot of gold. After a rough season, this could this be the life-changing fortune they desperately need.

The group cleans up and does a final gold weigh-in for the season. Meanwhile, Dustin leads the crew to a new mine site that quickly proves to have huge potential.

The Dakota Boys and their crew members reflect on their wild season and look ahead to what's next.
