An encounter with a devil leaves Red Sonja, the legendary swordswoman, bereft of her signature chainmail and fleeing murder charges, but a change of clothes and venue aren't enough to escape the guilt in her heart. Penniless and under pursuit, she has no choice but to accept a dangerous mercenary job: to search for the tomb of an ancient warrior queen. But the spirit of Queen Gheta lives on... a fierce and unnatural combatant who may be the only creature in history capable of defeating Sonja. Meanwhile, the demonic entity Bhamothes wreaks havoc in her homeland of Hyrkania... and only the forgiveness of a murdered boy can end its killing spree!
