Coming off of the recent deaths of his parents, troubled teen Ryan Cain moves in with his uncle Mark Cain, a renowned Archaeologist. Mark soon finds himself on an excavation in the Petexbatun Rain Forest; where the ancient Mayan civilization once thrived and then mysteriously disappeared. There he meets Tana, a native girl with a dark primal secret and they share an instant attraction.
Joining the Archaeologists is a team of Mercenaries hired by a wealthy Englishman—to find and bring back a mysterious ancient artifact. Not heeding the native’s warnings, they dig up an ancient werewolf Boki, who is bent on carnage and revenge. Besides the Cain’s, the only forces to stop him are the protectors—four indigenous women—Maya, Saki, Winooski and Tana who possess animalistic abilities similar to Boki, but not as heightened. Their only chance at defeating him is to fight together; which they did centuries ago. But the difference between then and today is Boki vows to never be entombed or defeated again.
