After war games were completed in the Fuji Training Ground, a mysterious storm sends First Lieutenant Akiyoshi Iba and his subordinates to the Warring States period, 400 years from the present time. Stranded, Iba wants to return to the present with the rest of his units. However another officer by the name of First Lieutenant Takuya Shimamura had wanted to alter the past in order to change the modern times when they head back. But as the days go on, the platoons find themselves under constant threats from the Samurai, with most of the soldiers being killed individually in ambushes and surprise attacks by the former and later, by Ninjas. The rest were wiped out in a surprise attack against Iba's camp, after Shimamura had been executed by decapitation, by a combination of Archers and Arquebusers.

In the end of movie, there only 2 survivor left. Miyashita from the Shimamura platoon live with his lover and the child together in the past time meanwhile another survivor, Sergeant Fukami Moe, had been able to return to the present after the same storm had brought her back from the Sengoku period. Unfortunately, she had lost most of her memory due to the traumatic experience that she had seen since most of her fellow soldiers and First Lieutenants Shimamura and Iba were killed in the Sengoku period, as well as being the only survivor when police had found her.
