Just another low budget film you know. The story is simple. An group of aliens arrive on medieval Japan. They are hungry so they kill everyone. Only some ninjas from the Inga clan will be ready to confront them. Yamata and his pals are also a group of mighty assassins and they will try to survive at any cost. The battle will be horrific and the bloodbath will be tremendous. Don't expect too much from this cheap production. Only fun, some acting, and lots of sword fighting. It is not the best action film you will ever try but it is worth seeing.
