In 1865 when the Shogunate is on its last legs; but still capable of punishing its enemies. Izo (Kazuya Nakayama); is an assassin in the service of Hanpeida (Ryosuke Miki); a Tosa lord and Imperial supporter. After killing dozens of the Shogun's men; Izo is captured and crucified. Instead of being dying; his rage propels him through the space-time continuum to present-day Tokyo. Here Izo transforms himself into a new; improved killing machine; his entire soul still enraged by his treatment in his past life. His ability to leap through time; slashing as he goes; attracts the attention of the lords of the universe in office for eternity. Izo; however; is not about to bow to anyone; even the lords of creation. In the final conflict; the Prime Minister (Beat Takeshi); calls in allies from all eras; from samurai swordsmen to the yakuza. It should be the most bloody and violent sword fight ever!
