In the wild interior of the Yucatán, far from the lazy beaches of Cancún, two young couples and some new-found friends venture to the site of an ancient Mayan temple, in pursuit of another in their group. What started out as a day trip spirals into a nightmare when they reach the ruins . . . and discover the terrifying presence that lurks there.
