The Hidden Fortress (1958)
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 before being sent away without any food. 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. After a prisoner uprising, Tahei and Matashichi slip away, steal some rice, and make camp near a river.
While building a fire, they find a piece of gold marked with the crescent of the Akizuki clan hidden in a hollowed-out stick. Looking for more of the gold, the peasants are discovered by a mysterious man whom they take to be a bandit. They explain how they intend to escape Yamana territory: rather than cross the closely-guarded border into the neighboring state of Hayakawa, they will travel to Yamana itself and then pass into Hayakawa. The stranger is enthused by their plan, so he shows them another piece of gold, and he leads them to a secret camp in the mountains where the rest is hidden. Unbeknownst to them, the man is a famous Akizuki general, Makabe Rokurōta. Although Rokurōta initially planned to kill the peasants, he changes his mind and decides to use their plan to bring the gold and Princess Yuki of the Akizuki clan, also hidden in the camp, to Hayakawa, whose lord has promised to protect them.
Rokurōta escorts Princess Yuki and the huge cache, 200 kan of the clan’s gold (still hidden in hollowed-out logs of wood), to Yamana, bringing Matashichi and Tahei to help carry the gold but kept unaware of Yuki and Rokurōta’s identities. To protect Yuki, he has her pretend to be a deaf-mute and has a decoy (Rokurōta’s younger sister) sent to the Yamana to be executed so they will believe that she is dead. During their travels, Tahei and Matashichi get the group into dangerous situations several times owing to their cowardice and greed. During a stop for the night at an inn, Yuki forces Rokurōta to buy the freedom of a captive young woman who had belonged to the Akizuki clan, who then refuses to leave them.
After losing their horses and obtaining a cart to move the gold, the group is spotted by a Yamana patrol, and Rokurōta is forced to kill them. While pursuing two stragglers, he accidentally rides into a Yamana camp, where the commanding officer, Rokurōta’s old rival Hyoe Tadokoro, recognizes him. Tadokoro is sorry he didn’t get to face Rokurōta in battle and challenges him to a lance duel. Rokurōta wins, but spares Tadokoro’s life before stealing a horse and riding back to the group. While in Yamana, they see worshippers gathering for the Fire Festival, so Tahei and Matashichi decide to hide the load of wood among them, but, since they are under the eyes of the Yamana soldiers, they are forced to throw the cart onto the bonfire and join in the ritual dance. Princess Yuki is quite taken by the philosophy behind the Festival regarding the shortness of life and the pettiness of the world. The next day they dig the gold out of the fire’s remains and take away as much as they can carry. One night as they approach the Hayakawa border, they are surrounded. Matashichi and Tahei manage to hide in the confusion while the rest are captured by Yamana soldiers and detained at an outpost. The two of them try to turn in Rokurōta for a reward, but having already captured them, the soldiers laugh at them and they leave for Hayakawa with nothing.
Tadokoro comes to identify the prisoners the night before their execution. Tadokoro’s face is now disfigured by a large scar which he explains is the result of a beating ordered by the Yamana lord, as punishment for letting Rokurōta escape. Yuki proclaims that she has no fear of death and thanks Rokurōta for letting her see humanity’s ugliness and beauty from a new perspective, and she repeats the ritual chant from the Fire Festival. The next day, as the soldiers start marching the prisoners to be executed, Tadokoro begins singing the same chant, and suddenly sends the horses carrying the gold running across the border. He frees the prisoners and distracts the guards so they can ride off, but Yuki tells him to join them. The entire group manages to escape across the border into Hayakawa.
Matashichi and Tahei, both hungry and tired, stumble across the lost gold carried by the horses and immediately start arguing about dividing it between them, before being arrested by Hayakawa soldiers as thieves. The peasants are brought before an armoured samurai and a well-dressed noblewoman. General Rokurōta and Princess Yuki finally reveal their identities to the astonished peasants. Thanking them for saving the gold (which will be used to restore her clan), the princess rewards Matashichi and Tahei with a single ryō on the condition that they share it. As the two men leave the castle to walk back to their village, they begin to laugh upon realizing that they have finally made their fortunes.
