The Civil War was just the beginning...

To help him attain victory over the Royalists, Oliver Cromwell has made a pact with the Devil. In return for his soul, he has been given a fearsome demon army – a blood-thirsty platoon of ancient evil... the Kryfangan! With Charles Stuart, the rightful heir to the English throne, seemingly killed in battle and his Scottish army slaughtered by the Kryfangan, Cromwell now has control of Parliament.

However, by the time the Kryfangan's real identity is revealed to Cromwell, it is too late to stop their relentless killing spree. And when the true nature of the Great Plague is exposed, London soon becomes a city overrun by zombie hordes. The English must put aside their religious, social and political differences as they find themselves caught between two armies of the dead waging war with one another!
