This is a very strange and rather creepy science-fiction film.
Cone helmet wearing invaders from the planet Neptune have landed on Earth. The world can only be saved from these slow moving and clumsy invaders by cape wearing Space Chief (Shin'ichi Chiba) and a bunch of Japanese schoolchildren...
This is pretty weird and awful stuff, the cheese factor is high though. Space Chief drives a rather suspicious looking "rocket car" and fights the invaders with a series of energetic though flimsy looking chops and judo throws.
