A bar brawl threatens Shawn's health and the future of the Christine Rose. Meanwhile, the Wild Ranger struggles with a leak and an injured crew member.
The weather may be perfect, but storms are brewing onboard the dredges as egos clash and tempers flare. Emily's first dive is almost her last when she learns the dangers of dredging first-hand.
The season is halfway over, and tensions are running high as the dredgers search for new sweet spots. An accident with the 15 ton excavator threatens to end one deckhand's season.
Simmering grievances come to the boil when Wild Ranger owner Vern fires one of his crew. Meanwhile, a jammed sluice box leads to a bitter fight between Zeke and Emily.
On the Christine Rose, a hastily welded winch roller gives way, releasing a cable that throws a crew member overboard. Scott insists on diving despite his injured leg.
As the season draws to a close, The Sluicey finally enjoys some success. Scott swallows his pride and invites Steve back to the Wild Ranger. But will he accept?
As winter descends on Nome, the crews make the most of the last few days of the season before facing off at an auction for next year's dredging grounds.
