A fundamentalist Louisiana farmer makes a desperate call to the Reverend Cotton Marcus (Patrick Fabian) to perform an exorcism on his possessed teenager daughter Nell (Ashley Bell). She' suspected of butchering the family's animals at night...as she wakes up covered in blood. Marcus is riven by religious doubt yet accepts the job for the money. He's accompanied by a sceptical documentary crew who film him as he realises he's up against something all too real. Chillingly effective horror in the style of the Blair Witch Project.
