Priest (2011)

A centuries-long war between humans and vampires has devastated the planet's surface and led to a theocracy under an organization called The Church. They constructed giant walled cities to protect mankind and developed a group of elite warriors, the Priests, to turn the tide against the vampires. The majority of the vampires were killed, while the remainder were placed in wikt:reservations. With the war over, the Clergy disbanded the Priests. Outside the walled cities, some humans seek out a living, free from the totalitarian control of the Church.
