In the first century AD, a group of Roman soldiers travel to a remote outpost in Roman Britain to investigate why all communication has ceased. They find the entire Roman settlement deserted and the inhabitants gone. There are no signs that anything violent had occurred other than the strange symbols drawn on the walls with foul-smelling mud. When night falls, however, the dead, under the thrall of a Briton necromancer, rise and descend upon the settlement, drawn to the scent of living flesh. A battle ensues and the soldiers must find the source of the necromancer’s power in order not to likewise join the legion of the undead.
