Living in poverty in Phoenix, Arizona in 1884, Jacob Waltz is the true-life old miner who has prospected for gold across America for his entire life, and failed. Then one day a friend from New Orleans comes to Waltz by night with an amazing story about a rich gold mine in the mysterious Superstition Mountains fifty miles east of Phoenix. But he says there's a problem with the map, and a danger in staking a claim, so it all must be done in secret. Reluctantly, Waltz accepts the invitation to guide his new partner and another man into the mountain range to the valley of the great peak, even though the hostile Apaches hold the Superstition Mountains sacred. Trouble ensues when two more strangers come to Phoenix, asking questions about Jacob Waltz and his new friends. Follow Jacob Waltz into the dark canyons of the Superstition Mountains and witness the legendary discovery of "the richest gold mine in the world."
