In December 7, 1941, five brothers exploring a shaft on an island off the coast of Washington State make an extraordinary discovery, but a tragic accident suspends further investigation. In the present, Juan Cabrillo and his Oregon team, chasing the remanants of a crashed satellite in the Argentine jungle, stumble upon a shocking revelation. His efforts to untangle the mystery lead first to that island, and then much farther back, to an ancient Chinese expedition and a curse more than 500 years old.
