An impressive battle painting in 16th century Japan. Far Eastern martial arts, fantastically choreographed: The sovereigns take advantage of the weakness of the old shogun, corruption and violence are omnipresent. Takeda Shingen is a schemer who wants the principality of the young Kagetora for himself. Kategora has just won the War of Succession against his power-hungry brother, Takedo suspects that he is weakened by this and even tries to drive a wedge between Kategora and his mentor and fatherly friend. But Kategora is strong and a skilful strategist. He recognizes the cunning of the attacker and sets a devastating, deadly trap for the advancing army.
