Študent antropologije Nathan povabi nekaj svojih sošolcev in profesorja Nasha na zapuščeni družinski ranč, kjer naj bi se predvsem zabavali in obudili starodavni obred. Na posestvu jih pričaka Nathanov moteni starejši brat in zadrogirani neznanec Delgado, ki je odločen, da se maščuje enemu izmed njih za dejanje iz preteklosti. Tako si druščina sploh ne predstavlja, kaj jih čaka.
A group of anthropology students take a road trip to the family ranch of one of them for a weekend of drinking and taking drugs, the latter under the pretense of researching ancient rituals. They run in trouble, however, because the brother that lives on the seemingly abandoned premises displays disturbing behavior in his search for a "bride" and a stranger named Delgado turns up to enact revenge for a misdeed in the past by one of the students.
