Gamera steps in repeatedly to stop evil aliens from taking over the Earth. Frustrated but still determined, the aliens search for a weakness in Gamera's armor finally deciding to use Gamera's fondness for children against him. Capturing two boy scouts Gamera had recently befriended and threatening to kill them unless Gamera follows their commands, the aliens succeed in implanting a mind control device into Gamera. Now they threaten to have Gamera wreck havoc and destruction upon the world unless humanity bows to their demands. And if their plot involving Gamera doesn't work out, the aliens have yet another monstrous surprise all their own named Viras at their disposal.
While I quite enjoy that portion of the film that actually features new footage of Gamera and Viras in action, a third of this movie seems to be made up of stock footage from previous Gamera films and the way the footage is used is disappointing, one action sequence after another after yet another to the point it really grinds the movie to an halt. It's really too bad as the alien footage features some neat albeit shocking images much more gruesome than is usual for this type of kids' movies and the final battle with Viras just has to be seen to be believed. All in all, this is good fun that should appeal to those young and young at heart but still, that third featuring stock footage is tough slugging.
