The miners of Nome continue their far flung explorations in search of new gold. Zeke and Emily head to Sledge Island and Shawn continues his dreams of gold at the Bluff. Meanwhile, the Kelly’s reputation may sink them before the season starts.

Desperate to find new gold, Shawn pushes himself and his equipment to the limit. At Sledge Island, the deeper water triggers dangerous side effects for Zeke. The Kelly’s go upriver for a shot at redemption.

Shawn's obsession with the Bluff reaches a tipping point. Zeke and Emily only have enough fuel for one more trip to Sledge Island. Undeterred by obstacles, Nome newcomer, George Young seeks his fortune on the Bering Sea floor.

Halfway through the season, Shawn Pomrenke needs to find a massive amount of gold at the Bluff or his empire could be ruined. After the debacle that was Sledge Island, Zeke and Emily reach a breaking point. Meanwhile, Nome newcomer George Young is buried in debt, but remains optimistic.

Anxious to reverse his fortunes, Zeke undertakes a perilous solo dive. The Kellys risk a thirteen-mile trip in their rinky-dink dredge. George is desperate to prove he's a capable diver before his brother leaves Nome.

A back injury hobbles Shawn. Kris puts the Kellys on gold, but the claim owner has second thoughts. George is in a tight spot when getting gold means defying his brother.

At the mouth of the Penny River, Emily saves Zeke from a generator fire. Kris strikes a devil's bargain with the last willing claim owner in Nome. George loses his ace diver and brings his son, Landen, up to dredge in the dangerous Bering Sea.

Injured, Shawn depends on his crew and the mercy of the murky Bering Sea to salvage the empire. Zeke and Emily land on a career-saving spot but toxic fumes threaten more than their season. George faces a final dive and cleanout to determine his fate.
