Matasaburo Tamba

Fils du vassal Takakura, le samouraï Shingo a une réputation de bretteur invincible qui lui attire les faveurs de son suzerain. Un jaloux cherche alors à désavouer Shingo en remettant en question ses origines. Mais il est accusé de diffamation et, dans un accès de rage, blesse à mort Takakura. À l'agonie, ce dernier avoue à Shingo qu'il n'est pas son vrai père et lui révèle les origines de sa naissance. Shingo devient alors un rônin (samouraï vagabond) avant d'entrer au service de Matsudaïra, un proche conseiller du shogun. Mais la guerre civile gronde et met en péril le régime shogunal…
