Space aliens arrive on Earth with their giant shark and intend to take over the planet, but first they must destroy Gamera.

A moon base is destroyed by a spaceship with a cluster of gumballs on its head. Later, at Sea World, dolphins are dying mysteriously. Zigra kidnaps two men and two children (one of whom is a Coke addict--Coca-Cola that is) and starts causing earthquakes. The two 6-year-olds somehow outwit Zigra and help their incapacitated fathers escape. The Zigra Woman, who can use her eyes to put people into comas, then chases them all over Sea World like in an extended Benny Hill skit. Somewhere in this movie Gamera finally shows up and fights Zigra, who turns into a giant swordfish.—Jonah Falcon <[email protected]>
