A humpback whale enters Tokyo Bay and causes a ruckus in the media and the general public. The bay is polluted and not really fit for a whale to live in. Under public pressure, the government decides to rescue the whale and forms a committee. Division 2 is called in to provide crowd control due to the fact hundreds of onlookers are on the shore of the bay. The rescue committee try several times to lure the whale out into open waters, but it keeps coming back. Why does the whale keeps coming back to the heavily polluted waters of the bay?
