After being vanquished by the Spanish empire, little remains of the Aztec and Mayan civilizations. From the ashes of their cities emerged a unified legend: Their conquerors possessed a mysterious artifact so powerful - so deadly - that it was universally known as the "Death Relic."

As Payne and Jones embark on a perilous mission to find the lost archaeologists, they realize that Maria's research may be the key to solving one of the darkest mysteries of the world.
