A Certain Killer

When a mysterious stranger muscles into two rival yakuza gangs, Tokyo's underworld explodes with violence.

Eddie Kenner is given a special assignment by the Army to get the inside story on Sandy Dawson, a former GI who has formed a gang of fellow servicemen and Japanese locals.

After yakuza boss Kurata dissolves his own criminal empire, a rival kingpin offers a position to Kurata's top operative, Tetsuya "Phoenix Tetsu" Hondo. When the fiercely loyal Tetsu declines, Otsuka taps unstoppable Tatsuzo the "Viper", a ruthless gun-for-hire, to assassinate him. As the Viper trails his target through the countryside, the agile Phoenix Tetsu grows concerned that one of his former associates has betrayed him.

After botching his latest assignment, a third-ranked Japanese hit man becomes the target of another assassin.
