The first night dive of The Clark's season goes horribly wrong, and the next day takes an even bigger emotional toll as a jammed sluice box leads to a bitter fight between childhood friends Zeke and Emily. Over on The Sluicey, Scott Foster's solo dive is a bust when Ian's anti-thrust system fails, sending rocks tumbling through the water onto Scott's head. The Christine Rose's crew continues to be saddled by injuries — and left struggling to meet the huge barge's massive costs. Meanwhile, The Wild Ranger is a dredge in freefall, suffering personality conflicts and mechanical breakdowns. With the dredge stuck in port waiting on parts, a sluice box cleanout turns into the one of the most explosive confrontations of the season. And as the weather turns bad, a few stressed-out crews head to a volcanic hotsprings for some R&R — but the trip ends in disaster on many levels.
