With the League of Assassins knowing where the SoulTaker Sword is, but unable to get Katana to return it, they decide their only course of action is to kidnap Bruce Wayne and hold him for ransom - that ransom being the sword. Of course, they don't realize that Bruce Wayne is actually Batman! When Katana shows up to turn over the sword and rescue Wayne, Alfred causes a diversion, allowing Wayne to don the Batman suit and join the battle. Teaming with Katana to end the League, Batman finds himself in an all-out ninja fight that ends with a startling revelation.
Batman once more patrols the streets of Gotham City. Batman brings justice to the likes of The Joker, The Penguin, Professor Pygg, and more treacherous forces seeking to blanket the city in their arcane menace.
Along with backup from ex-secret agent Alfred and lethal swordstress Katana, the Dark Knight faces the twisted machinations of Gotham City's criminal underworld led by the likes of Anarky, Mister Toad and Magpie.
