Under the disguise of a newly assigned priest from the small village of Cheddar and concealed a dangerous vampire, Cheddar Priest silently killed several people until villagers were able to expose the culprit. Unfortunately for them, that only resulted in a slaughter—much to vampire's great delight.

What happened in Cheddar did not escape the attention of the local authorities. They sent a police squad there with the young police officer Seras Victoria. Nor it escaped the attention of the Hellsing organization and their best expert in supernatural threats, Alucard.

Cheddar Priest was then left to wait for them, accompanied by his new ghoul minions: an armed pack of mindless animated corpses, those who fell prey to the vampire.
