In a gold mining town hidden among the mountains of New Mexico, a black digger was detained who was trying to bring to light mummified human remains. The investigation into the circumstances of the death of the unknown person is entrusted to FBI special agent Corinna Swanson, who, in turn, turns to archaeologist Nora Kelly for help. The appearance of the mummy indicates that this man died in terrible agony, and an old golden cross trimmed with precious stones was discovered next to the body. What if this treasure is from that legendary treasure hidden in the mountains by the Pueblo Indians during the era of Spanish colonization? Only the dead man knew the answer to this question... But who is he, will it be possible to establish his identity? Why do the remains emit strong radiation? There are clues, but the closer to the truth, the more strange deaths... For the first time in Russian!
