The stakes get higher at the Porcupine Creek prospect as reality sets in about just how little time they have to get to their gold. The miners start to rebuild the mining ghost town but the bears aren't so keen on their new neighbors — and they let them know it.

The crew races to set up the mining plant and start running dirt. When the families arrive from Oregon and question the lack of gold — and master mechanic Harness becomes dangerously ill — the tension builds so high that Dorsey and Todd almost come to blows.

The team attempts to finally run potential pay dirt through the wash plant. But a visit from the Department of Fish and Game reveals a violation, jeopardizing their vital water supply to the mine. Then disaster strikes as Todd's daughter fights for her life.

The miners continue to run dirt but an equipment malfunction brings the operation to a halt. Meanwhile, James Harness collapses and Jimmy Dorsey drives a wedge between himself and the crew when he takes on an extra job to earn cash. But hard work late into the night finally hits a pay streak.

The miners' futures are on the line at Porcupine Creek. After 80 days, the miners are behind schedule, and the Hoffmans have run out of money and deliver the crew an ultimatum: find $10,000 worth of gold in the next two days, or the families have to head home to Oregon. Meanwhile, after Dorsey struggles with the wave table, tensions flare and fists fly.

With winter weather closing in, a gold recovery expert comes to help the rookies. Todd discovers a major design flaw in the equipment and is forced to make huge modifications. With the credit cards maxed out, he is forced to take desperate measures.

The crew remains in deep financial hole. Veteran miner "Dakota" Fred thinks he can turn things around and he cranks up production faster than ever before. But when things start falling apart, tensions mount and Harness can't keep his frustration in.

Desperate to get to bedrock and large quantities of gold, Todd and Jack throw caution to the wind and dig deeper than ever before. With the brutal Alaskan winter threatening, they battle floods, cave-ins and equipment breakdowns.

With the arctic winter looming, the crew races against the clock. Rain and thawing snow flood the mine and Jack puts his life on the line as the glory hole caves in around the massive 100,000 pound excavator.
