The film is a human drama starring Somegoro Ichikawa and Younha. Younha plays Sora, a Korean high schooler. She chases after a boy she likes who has moved to Japan for college, but after she gets there, she discovers that he has returned to Korea due to family circumstances. She remains in Japan, but things eventually end in heartbreak for Sora. Shortly after, she runs into an odd man called Matsumoto (Ichikawa), who works multiple jobs to pay off his debts but also spends his time gathering discarded glass bottles. With her video camera, she begins documenting Matsumoto and his bottles, and in the process, she regains her lost smile.

In response to Japan's request for a countermeasure against Godzilla, UN engineers construct Mechagodzilla, a giant robotic version of Godzilla. Nonetheless, Godzilla proves himself a force to be reckoned with against this monstrosity and battle ensues.
