SPOILER: This silly but enjoyable film begins with an airplane being sliced in half by a ray. Then the ray is revealed belonging to a ray firing, flying, man-eating super vampire monster named Gyaos. But when Gyaos tries to eat a boy named Eiieechi, it's Gamera to the rescue. Gamera saves the boy, but almost gets his hand sliced of by Gyaos's ray. Gamera heals his wounds again and arrives when Gyaos attacks Tokyo. He manages to bite off Gyaos foot but is again hurt in the process. So the foot floats ashore and scares people. Then it is discovered that Gyaos can be hurt by sunlight and will die if exposed to the sun. So they decide to make a spinning fountain of drugged blood and Gyaos will get dissy and drugged and not be able to return to his cave and will die in the sun when it reaches dawn. However, a malfuntion in the mechanism causes the plan to fail. This is a good Gamera adventure with a zany plot and good effects.
