He is a nightmare that has claimed worlds, that the Psi-Judges didn't predict, and that even Judge Dredd cannot prevent. If his vile plan succeeds, our world will never be the same. His name is Sabbat, he has the power to raise the dead - and he's already here.

While the cities of the world fight for survival against incalculable zombie hordes, Dredd must help an international squad of Judges to locate and terminate Sabbat. But help is coming from an unexpected source - the future mutant bounty hunter and "Strontium Dog" Johnny Alpha, hot on the necromancer's trail!
