Hellsing, a supernatural threat-response agency, is sent to destroy a vampire who is converting the villagers of Cheddar into ghouls. To put a halt to this, the organization's commander, Sir Integra Fairbrook Wingates Hellsing, deploys her most fearsome asset: Alucard, a strong vampire. Alucard, armed only with a single pistol, wreaks devastation on the creatures that plague Cheddar. Seras Victoria, a young police officer, is caught up in the pandemonium and is fatally injured as a consequence. Alucard, moved by the girl's plight, offers her the option of dying as a human or continuing on as a vampire. Seras accepts his offer and begins a new life as a member of Hellsing.
