Aliens from a distant planet bring a giant shark monster to earth in an attempt to take over the oceans.
the aliens have taken over the body of a beautiful woman and use her to help in the invasion. Two bratty little kids constantly foil her attempts. She is always chasing these kids around much like an old Abbott and Costello routine!! My God, I can't believe I watched this.
Soon Gamera is fighting the shark monster called Zigra and the highlight is Gamera using the beast as a musical instrument!! I kid you not. But it does prove that you can tune a piano, but you can't tune a fish!!
Laugh filled sci-fi film that only die hard Gamera fans will like. Mill Creek has a beautiful print however.
