The final Gamera film involves a young woman who finds an egg that a monster hatches from. She actually decides to raise the monster as her pet, but things get a little out of hand as the beast gets bigger and bigger.
Gamera shows up and has to fight the monster in a battle that Japan and the world may not survive. He also has to contend with a flock of Gyaos monsters as well. The Gyaos take a back seat to Iris once the monster is full grown. It is unique and very convincing.
If you're a Gamera fan you will want to see this. This concludes my reviews of all 11 Gamera films from 1965-1999. Some of it was very hard to get thru, but this film more than made up for it.
