With less than a week remaining in the season, every crew is battling the clock. Just when they think it couldn't get any harder, a massive storm descends on Nome.
This winter, strict deadlines force the fleet to take extreme measures. Vern gambles on an advanced dredge and Emily unleashes a team of all-girl divers on Nome.
Just as the fleet seems set to home in on the gold, equipment problems cause setbacks, costing each crew precious time under the water.
Shawn runs out of fuel and sets out on a dangerous trek to a remote town for supplies, while Kris Kelly deals with an equipment breakdown on the Paddy Wagon. Meanwhile, Emily loses the trust of her crew when she reacts poorly in an emergency situation.
All the teams are working hard to make the season pay. But they will have to contend with the weight of the past before they can land on future riches.
After a month out on the ice, one day remains in the ice-mining season. For every miner, that's one more day to prove that a season full of risks was worth the cost.
