After witnessing his wife burned at the stake, warlord Khalar Zym sets out on a quest to find the mythical Mask of Acheron, an ancient artifact that will bring his beloved back to life. In his search across the lands, Zym destroys a village in northern Cimmeria, where a boy born of battle survives and is cast out into the world, alone. Years later, Zym crosses paths again with the boy who survived-Conan. He must now contend with this barbarian nuisance who is now set on vengeance for the slaughter of his village. Zym and his daughter, Marique, eventually clash with Conan in an epic final battle, the outcome of which will decide the fate of the world.
