A once-in-a-lifetime treasure hunt is a dream come true for archeology intern Kay Gerard. On the fringes of the ancient Mayan city of CobA, Kay and her mentor, Dr. Santiago Ramirez, begin excavation on two remote temples. Their treks into the site reveal the local populationas curious ties to the ruins, and Kayas interactions with the people they encounter, especially the children, are somewhat unnerving, yet she largely ignores the ominous feelings due to the excitement of the dig. As they get close to entering one of the temples they collide with dangerous looters, forcing Kay to flee into the jungle. The more desperate her situation becomes, the more determined she is to survive and soon finds herself in a situation with no other option except to fight for her life in the deadly ruins of Mexicoas unforgiving jungle.
