Odo residents travel to Tokyo to demand disaster relief. The villagers' and reporters' evidence describes damage consistent with something large crushing the village. The government sends paleontologist Kyohei Yamane to lead an investigation to the island, where giant radioactive footprints and a trilobite are discovered. The village alarm bell is rung and Yamane and the villagers rush to see the monster, retreating after seeing that it is a giant dinosaur, which then roars, and returns to the ocean.
