Ogami rescues a prostitute and offers to be punished in her place (which means being beaten to within an inch of his life). Impressed by his fortitude, a Chamberlain hires Ogami to assassinate a ruthless Governor, only to find out that the same Governor wants Ogami for a mission of his own.
When Ogami refuses the Governor's offer, he must face a series of assassins, including a dangerous gunslinger, a master swordsman and an army of soldiers. And to make matters worse, a former samurai keeps politely asking if they can have a duel!
