Two small-time thugs, Yusuke Shura (Kojiro Shimizu) and Ken Hayami (Yuji Kishimoto), return to Japan from the US after a decade away. Having helped carry out a vendetta as hitmen ten years prior, they are once again asked to act as bodyguards for the Gondo-gumi. The Gondo-gumi had been committing a string of crimes, amassing influence not only in Japan but also across Southeast Asia. Determined to rescue a Chinese woman being held hostage, the pair take on the organisation.
