Lost Gold of The Aztecs

Legend has it that five hundred years ago a vast fortune in gold was hidden by the Aztecs somewhere in the American southwest. Now three families are closing in on what they believe is the location of the treasure.

The Dillman Family continue their grandfather's 56-year search by completing the underwater dye test at Shadow Cave, which may reveal more than they bargained for. In Nevada, the Miners bring in a Cave ROV.

The hunt begins to heat up when the Miners in Nevada use a smoke gun to find another entrance to this dangerous tunnel system. In New Mexico, the Villescas family has to use some crossbow ingenuity to find their way into a sketchy mine.

After a few hits and misses, the Dillman family seek answers in the mysterious Weeping Cave, where they look underwater for evidence of the Aztecs.

The Villescas family talk with an expert about whether a spur they found could tie to the Conquistadors. The Dillmans use drones to locate an important ancient symbol, which could be a map. To find out, they must repel down the side of the canyon.

In New Mexico, the Villescas family decide to risk everything by bringing in more heavy machinery and a full crew for one final push to find Conquistador gold. In Nevada, the Miners' years of Aztec research is threatened.
