A group of American friends, including the pragmatic Jonathan Tucker and the adventurous Jena Malone, embark on a carefree vacation in Mexico, seeking sun and escape. Their journey takes a sinister turn when they are persuaded by a charismatic stranger to explore a remote and ancient Mayan temple deep within the jungle. What begins as an impulsive detour into the unknown quickly descends into a desperate fight for survival as the ruins reveal they are not merely abandoned stone, but a living, malevolent entity with a will of its own. Trapped and isolated, the bonds of friendship are tested by paranoia and supernatural forces that prey on their deepest fears. Directed by Joe Wright, this tense supernatural thriller crafts an atmosphere of escalating dread, where the true horror lies not in what they find, but in what finds them.
