The film is about a small, hot spring town in Japan, where a ferocious ancient shark reawakens and terrorizes the local hot spring facilities. As the threat escalates, the townspeople band together to protect their beloved town from the menacing predator. The thriller-comedy marks the directorial debut of Morihito Inoue, two-time winner of the National Independent Kaiju Film Championship. It premiered at the 2024 Tokyo International Shark Film Festival, where it took home the Audience Award, and was released in Japan and other international territories last year.
