Plot
A band of ninja warriors, led by an Iga ninja named Yamata and his comrades Jinnai and Nezumi, are assigned to investigate the crash of a mysterious object from the sky. Upon arriving at the crash site, they discover the remains of other ninjas that have been brutally torn apart. Shortly after joining forces with another band of ninjas led by the kunoichi Rin, they encounter a boy whose village was massacred by an unknown assailant. Before they can get any further explanation from him, the ninjas are attacked by the assailants, who reveal themselves to be aliens from another planet. After a grueling battle that takes the lives of several ninjas, Yamata, Rin and Jinnai kill three of the aliens, but one of them retreats and takes Jinnai with it. A cowering Nezumi rushes back to his home village, only to see the villagers massacred by the aliens. He runs for his life, but is cornered by the alien, which swiftly decapitates him as his head lands on a temple post for a crow to feed on.

Jinnai wakes up at an abandoned temple, hanging upside down along with corpses of other ninjas. He discovers an organism lurking within his throat, but before he can react, it takes over his body. The boy leads Yamata and Rin to the temple, only to be surrounded by Jinnai and the dead ninjas, who are being manipulated by small organisms secreted from the alien's nostrils. The possessed Jinnai and the dead ninjas utter English expletives before Yamata takes one down to shut them up. After discovering a pair of eyes peeking from a dead ninja's mouth, Yamata tells Rin to target the dead ninjas' throats. Rin dispatches the ninjas by ejecting the organisms from their throats while Yamata shoves his hand through Jinnai's mouth to extract the symbiote controlling him. After a long struggle, Yamata frees Jinnai from the alien's control. Yamata then squares off against the last alien in a cave. Overpowered by Yamata's skills, the alien sprouts wings to fly out of the scene, but Yamata grabs its leg before taking off. The alien attempts to shake Yamata off its back, but Yamata places a bomb on it and jumps off before it explodes. Yamata lands safely and reunites with his comrades before they return home, unaware that the boy has one of the organisms in his bag.
