For decades, Ustaz Qodrat has used his religious teachings and knowledge to perform exorcisms but he failed to exorcism his son Alif who was possessed by a demon named Assuala. To find out why he had failed, he returns to the source of where he learned his teachings - Pesantren. He finds that the village is no longer the same for there are dark and disturbing forces there. In a final confrontation with the devil, Qodrat must choose to either avenge for his son, or to return to his true calling.
