A dark, dramatic story of the supernatural inspired by the Wagon Box Fight of 1867 in the Wyoming Territory. Lewis Tanner has run from his home in Tennessee and, after a series of crimes and misadventures, finds himself on a woodcutting crew at an Army fort in the middle of Indian country. After his crew is ambushed by Native forces, Lewis is forced into a group that rides out for revenge. But the woods are bad. Strange forces are at work there, and soon, his fellow fighters are found eviscerated. Lewis must fight for survival as otherworldly forces hunt him and his companions through a place they were never meant to enter.
