When Lt. Yoshiaki Iba arrives with his troops at a selected place to start a war exercise, they are being transported through time four hundred years ago at the warring era. They find various samurai clans and camps that fight each other in order to take advantage and power. Iba meets Kagetora, a fearless warlord and they become best friends and comrades. They have big plans to rule over Japan but the battles are so difficult that Iba's squadron soon starts having casualties. Even ten soldiers using modern weapons can't defeat the huge army of Shogun and his generals. Iba thinks now that he have to end this story and become a hero in order to escape forward in time but can it be true? One of the best action films ever seen with the incredible Sonny Chiba starring and delivering the icon of a idealistic and egomaniac fighter who lives only to fight and realizes that his dream maybe can be true at another history era. Great action scenes and fast direction for a Japanese production make this film a classic for Chiba's fans and not only.
