A strange new plague sweeps in from the east, raising the dead once more and turning them into famished revenants desperate for living flesh. Feared gangster Grant is serving a whole life sentence at one of the toughest prisons in the country. For him the outbreak is an opportunity. He escapes from prison and soon his psychopathic traits become a godsend to a small group of survivors holed up in the countryside. But old habits die hard and the reappearance of a fanatical prison warden soon tests Grant to the limit and threatens the redemption he so desperately craves.
