Gamera vs. Gyaos

A series of volcanoes erupt in Japan. The eruption at Mt. Futago (in Shizuoka Prefecture) attracts Gamera, whose arrival is witnessed by a young boy named Eiichi. Gamera then climbs up and into the volcano. A research team is dispatched to the volcano to find Gamera and study the effects of the eruption. Meanwhile, Chuo Expressway Corporation is building a roadway nearby, but local villagers refuse to leave.
