Two brothers embark on a violent revenge mission and discover that long-standing rumors of occult experiments among the Nazis were in fact rooted in reality. Three years before the onset of World War II, the Third Reich contacted the Wollners -- a poverty-stricken family of German-Americans living in Town Creek, WV -- with a lucrative offer to host visiting scholar Professor Richard Wirth. Completely oblivious to the occult experiments that were being conducted by the Nazis and Professor Wirth, the Wollners accepted. That decision would haunt their family and their town for decades to come. Flash forward to 2007, when Victor Marshall (Dominic Purcell) vanishes into thin air while camping near Town Creek. Determined to discover the true fate of his missing brother, floundering 25-year-old Evan Marshall (Henry Cavill) searches for answers. Just when it seems that there are none to be found, Victor suddenly reappears with a claim that he was abducted and then staged a daring escape. He asks Evan to gather some guns, pack the boat, and return to Town Creek with him on a mission to exact justice on his kidnappers. Upon returning to Town Creek, the two brothers come face to face with a terrifying evil born of an unholy union between Hitler's Third Reich and forces beyond human comprehension.
