"What is it about the temple of Ah-Qal? Why has no man ever returned with his sanity intact?" Thousands of years ago, the great king Ah-Qal was buried with a set of stone tablets that contained priceless knowledge. Since then, many people have tried to locate his tomb in the South American jungle, but most have returned empty-handed.

Ignoring all the warnings, they try to find the long-lost burial chamber of Ah-Qal. But as their search continues, Charley Manners and her colleagues start to realize that they might not be alone. All those years ago, what kind of evil did Ah-Qal leave behind to guard his treasures?
