Borderland (2007)

"Borderland" mixes a Mexican drug gang,  human sacrifice, American tourists, and Sean Austin as a convincing murderous cult member into a thrilling horror film. It's about three friends enjoying a weekend of booze and loose women before moving on with their lives. When one of them is kidnapped for use in a Santeria ritual that is supposed to grant the cult members the power of invisibility, the two other friends do what they can to save him. With the help of a bartender and a former cop whose partner was brutally murdered by members of the cult, they break into the drug lord's compound moments too late. Retribution on both sides is sought and leads to a bloody, violent climax. This movie is one of After Dark Horrorfest's 8 Films to Die For.
