A folklore professor becomes unwittingly possessed by the ancient Japanese demons of Thunder and Lightning. But when The Bureau of Paranormal Research & Defense dispatches a team of agents to investigate, a cursed samurai sword sends Hellboy (Ron Perlman) to a supernatural dimension of ghosts, monsters, and feudal mayhem. Now while pyrokinetic Liz Sherman (Selma Blair) and fishboy Abe Sapien (Doug Jones) battle one very pissed-off dragon, a lost and cranky Hellboy must find his way home.
