A failed assassination attempt brings into Freeman's possession Muramasa, the Devil's Sword, an ancient samurai blade that brings misfortune and death to any who possess it. Wishing to spare Freeman and tame the sword's malevolent spirit, Tiger Orchid, Freeman's wife, takes the blade to Kowloon to train with a legendary swordmaster. But she'll need to find him in Kowloon Castle, a slum so riddled with crime and destitution that it officially doesn't exist.
Its dangers are all too real, and even a possessed sword may not be enough to stop a gun-toting criminal army bent on selling Tiger Orchid into slavery!
