Kakushi-toride no san-akunin

Two bedraggled peasants, Tahei and Matashichi, sell their homes and leave to enlist with the feudal Yamana clan, hoping to make their fortunes as soldiers. Instead, they are mistaken for soldiers of the defeated Akizuki clan, have their weapons confiscated, and are forced to help dig graves. After quarrelling and splitting up, the two are each captured again and reunited when the Yamana force them alongside dozens of other prisoners to dig through the ruins of the Akizuki castle for the clan's secret reserve of gold. Tahei and Matashichi then meet a mysterious man, General Makabe Rokurōta, who guides them to a mountain fortress, where they help carry a large cache of gold and a princess, Yuki, to the neighboring state of Hayakawa, whose lord has promised to protect them.
