John Carpenter's Vampires

A bunch of vampire hunters aided by the Vatican are asked to hunt down a master vampire and his goons of vampires who are ripping and tearing humans apart. While the leader of the vampire hunter does the slaying and takes orders from the Vatican as his parents were killed by vampires and he was raised by the Church, the Church has an agenda of their own regarding a centuries-old cross from falling into the hands of the master vampire.
