Express Engineering Corp is building a highway in the forest near Mt. Fuji. Challenged by local villagers, foreman Shiro Tsutsumi and his crew are plagued with protests and sabotage.

Gamera vs. Gyaos – The Movie
A small boy, Eiichi Kanamura, grandson of the village elder Tatsuemon Kanamura, finds reporter Okabe snooping around. Okabe and Eiichi check out a strange light – which leads them to the cave where Gyaos, a giant bat-like bird-monster, is currently residing.
Running for his life, Okabe ditches Eiichi at the cave – but runs into Gyaos who devours him. Shiro and his crew (who are also checking out the light from the cave) arrive just in time to see an epic battle where Gamera and Gyaos exchange blows (with Eiichi in the middle).

After alerting the public about Gyaos and his abililties, zoologist Dr. Aoki investigate Gyaos’s prehistoric origins. The public is put on alert – stay indoors at night – Gyaos is nocturnal.
But after another battle with Gamera, Gyaos seems to be the victor, as Gamera tends to his wounds at the bottom of the sea. Even after using light flares to annoy Gyaos, the Japanese Self-Defense Force is still annihilated by the monster.
