A humpback whale enters Tokyo Bay, causing a media frenzy and public outcry. The bay is heavily polluted and unsuitable for the creature. Under pressure, the government forms a rescue committee to save the whale. Division 2 is deployed to manage crowd control as hundreds of onlookers gather at the shore. The committee attempts multiple times to lure the whale into open waters, but it repeatedly returns to the polluted bay. The narrative explores the mystery behind the whale's persistent return to such an inhospitable environment despite the efforts to relocate it to safer waters.
