Hellsing, an organization dedicated to eradicating the vampire threat, has recently uncovered information concerning the attempted production of "man-made" undead. The world is currently in the midst of WWII, and Hellsing's current leader fears that the Nazis could potentially use these creatures as front-line super-soldiers. Although the technology for creating artificial vampires is still in its infancy, it has advanced sufficiently to pose a serious threat. In an effort to halt this perverse and dangerous experimentation, Hellsing has dispatched two of its most skillful agents to Poland: a young man named Walter C. Dornes, also known as "The Angel of Death," and Alucard, an ancient vampire currently in forced service to the Hellsing Organization. Together, they attempt to stop the progress of the Nazi's efforts.
