Police Chief Sebastian Calderón has left Cape Cod for Mexico to track the fugitive bioengineers of an illegal Quetzalcoatl. His only source of information is the mysterious Tezca, a woman he doesn’t trust. During his investigation, he is ambushed, rendered unconscious, and awakens to find himself trapped in a stone chamber. No one knows where he is, neither his daughter in Paris, nor his Deputy back home—who is pursuing a lead that will take him to a fateful outcome. There is no way out of the tomb and Calderón suspects it was Tezca who put him there to die.
