In the final days of WWII, an earnest but somewhat dense sailor (played by Buster Keaton) is lost at sea. Months later, he makes a landing, but, not realizing that the war is over and thinking that he is in Japan, he surrenders to Mexican police, who mistake him for a serial killer. Thrown in a jail cell with an American thug, he is to be hanged next morning, when suddenly a rocket scientist offers him and his cellmate a chance to avoid execution if they pilot an experimental atomic rocket to the Moon.
