Just as best friends Boco, Joe and Junichi are confronting the bully who took their money, they hear a loud noise coming from the sky.

Brody claims to have some top secret information about where the kaiju threat might be, and he wants to go check it out with his new pals.

While aboard a high tech Eustace Foundation ship, the kids hear about a kaiju attack on a passenger liner — and they might be the next target.

The kids are brought to an island base for further testing, causing a rare rift between Boco and Joe. Meanwhile, James tells Emiko that he wants out.

While the military undertakes a top secret mission to save Gamera, Boco sends a message out to Joe. Then suddenly, Gyaos attacks.
