During the family trip in Okinawa, a lethal bomb is attached to Shiro’s butt accidentally! This incident is noticed by the Unidentified Nature Team Inspection, also called “U.N.T.I.”, and they start a recovery operation. At the same time, this secret is stolen by a mysterious terrorist organisation "Hinageshi Opera Company". Although the Nohara family has protected Shiro from these U.N.T.I. and Hinageshi, they learn that the bomb is powerful enough to destroy the Earth and cannot be separated from Shiro. The only way to save the world is to send Shiro to Space and detonate the bomb! Can Shinchan save Shiro from 6.5 billion people on the Earth?
