Masamichi Toyama is a loyal husband with a bad gambling debt. Mobsters out for the money track him down, beating him and raping his wife. Desperate for revenge, he makes himself a sword and sets out to wreak havoc. When he meets the Gonin, a group of five female thieves, his luck only gets worse. Run, Sayuri, Shiho, Saki and Chihiro are fast-shooting, strong-arm women. Not only that, but they're more than prepared to take on an army of gangsters. Unfortunately for them, they stole the ring Masamichi wanted for his wife, and now he's more likely to hunt them than join their cause.
When the Russian mob kidnaps the daughter of a reformed criminal, he rounds up his old crew and seeks his own brand of justice.
