In the season premiere, Parker, and his crew - Tyler Mahoney, Danny Etheridge and Dr. Diego Lazarzaburu - arrive in Peru to follow in the footsteps of the legendary Incas as they chase down historical leads and battle the jungle in their hunt to mine virgin ground. As Parker looks to partner up or mine alongside the world's toughest gold miners, he and his crew must first traverse inhospitable terrain and cross raging rivers. En route, the crew works with a gold miner who shares mining strategies passed down by the Incas, in addition to a mining family who share key insight on how they've mined their land across multiple generations. While they have a promising start, a flood of biblical proportions threatens to leave Parker and the crew stranded.

Parker prospects La Rinconada mountain, the highest gold mine on earth and a nearly lawless boomtown filled with 60,000 miners. Parker discovers big gold using hand-lit explosives, but a sudden illness threatens to end the trip early.
