Jack Reilly travels to Colombia on behalf of his new employer, the Tactical Archaeological Command, a clandestine organization whose objective is to locate and, if necessary, protect historically valuable assets around the globe. The former Delta operator is sent to investigate the violent kidnapping of veteran TAC agent Lorenzo Matias. But this is more than just a missing person's case. Seconds before Matias was abducted, he sent an encrypted message to his and Jack's superiors back in the United States. It read, "El Dorado exists!"

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

Twenty miles east of Devils Tower, in the sleepy town of Cascade, Wyoming, a cryptic letter is found. It mentions a "wealth of a nation", and reads as nothing more than fanciful fiction, except that its author was one of the most influential men in American history, famed explorer and former President of the United States, Theodore Roosevelt. The letter also references the Seven Sisters of Native American folklore. The correlation between the two subjects is unknown, even to Chatan, the message’s discoverer, a young man with Lakota ancestry.

Unverified reports tell of a hidden treasure trove deep beneath the Owl Mountains in Poland. Many have tried, but all have failed to locate the legendary Nazi gold train. Jack Reilly mourns the loss of his grandmother, a Holocaust survivor, and an esteemed historian. In memory of her, the retired Delta operator tours the place of her imprisonment, the Auschwitz-Birkenau State Museum, site of the infamous Nazi concentration camp.
