Dark Horse Comic's popular cult superhero Hellboy makes the leap from the comic book pages to the big screen. In the final days of World War II, the Nazis attempt to use black magic to aid their dying cause. The Allies raid the camp where the ceremony is taking place, but not before a demon - Hellboy - has already been conjured. Joining the Allied forces, Hellboy (Ron Perlman) eventually grows to adulthood under the supervision of his adopted "father" (John Hurt), serving the cause of good rather than evil. When the powerful and evil Nazi wizard who unleashed Hellboy suddenly reappears in modern times, he discovers that Hellboy is now working as a paranormal investigator at a secret U.S. government agency dedicated to protecting humanity from the forces of darkness. Now, Hellboy must fight to prevent the destruction of mankind.
