This horror film is derived in part from the real life story of cult leader Adolfo de Jesús Constanzo. The story begins in Mexico with two local policemen attempting to gain access to what appears to be an abandoned dwelling. Upon entering the home, Ulysses and a fellow officer are confronted with the gruesome remains of animal and human sacrifices. But, the home is not abandoned as they had imagined, and the two men are captured. Ulysses' partner is tortured and beheaded by the members of the cult occupying the home. However, Ulysses is shot but allowed to live in order to send a message to other law enforcement agents. Skip forward one year as three college students decide to head to the Mexican town for a fun time. Before they know it, Ed, Henry and Phil find themselves in the middle of a frightfully deadly situation. The horror and suspense that follows is sure to keep the viewer on the edge of their seat until the very end.
