A dangerous bomb known as Hysteria, created by a mad scientist, has the power to destroy the Earth and is programmed to explode upon any slight touch. Three robots—Louis III from the US, Robonof from the USSR, and Astro Boy from Japan—are tasked with disposing of the bomb somewhere far from Earth. They are escorting a space cargo train carrying the bomb as it heads toward Pluto.
