An Invention laboratory is working on the creation of a performance 'bomb' in the shape of a rocket that could be delivered to the front in order to entertain and amuse the national troops. Inside this rocket would be tiny performers. Once launched from the laboratory and landed amidst the Japanese troops the soldiers could enjoy the performers. The laboratory succeeds and the rocket is built. It bears the insignia, 'until the victory days.' The Japanese government began a program of shooting and disseminating propaganda and entertainment movies for its troops during World War II. Only 15 minutes of the film survives.
