Fiction follows fact in this gruesome tale of horror down Mexico way from director Zev Berman. Based on an occult-based murder spree involving human sacrifice in 1989, the plot revolves around three happy-go-lucky Texas University students, Ed (Brian Presley), Henry (Jake Muxworthy) and Phil (Rider Strong), who, nearing the end of their studies, decide to take a little R and R south of the border. Setting up Phil for his first sexual experience, the boys meet Valeria (Martha Higareda) and her cousin Lupe (Francesca Guillen), down some magic mushrooms and set off for the carnival. As the hallucinogens take hold, the boys get separated, and Phil, accepting a lift home, is abducted by his worst nightmare. A similar fate soon awaits his friends, as they become the sacrificial lambs, used by a religious cult of Mexican drug-runners to bestow mystical protection to their activities.
