Usagi and Jotaro are trapped in an isolated fishing cabin with Yagi - the badly wounded renegade assassin known as Lone Goat - and his young son, Gorogoro. Meanwhile, the local gang lord is amassing swordsmen from the area, waiting for his chance to attack the beleaguered samurai and claim both the reward for the assassin and the chance to name himself killer of the legendary Lone Goat and Kid.
