Dominion: Prequel to the Exorcist 2005

Having lived through traumatizing events during WWII, Father Lankester Merrin takes a sabbatical from the Church to conduct archaeological excavations in British-administered East Africa. Merrin unearths an ancient Byzantine church believed have been built and then immediately buried to keep down evil from the crypt below. The natives are convinced that uncovering the church has unleashed a demon, and begin to violently clash with the British military troops. As the village rapidly disintegrates into chaos and war, a disabled and terribly injured local boy befriends Merrin and his condition begins to radically and implausibly improve. Is it a miracle from God, or something more sinister?
