G.I. Samurai

Nobody in Lt. Yoshiaki Iba's (Sonny Chiba) unit can say how a Self-Defense Force exercise ended in the middle of Japan's warring states era, with rival clans fighting over who will be shogun. Kōsei Saitō drops the soldiers, with their rifles and vehicles, among men who carry swords and have never seen a gun. Iba must decide whether to hold his squad to its modern orders or take a side in a war that is already underway, and the men around him are watching.
