'Lucky' Louie the Lug has slipped by the police at a space port and boarded the first commercial flight to the Moon. Astroboy pursues him seeking to recover stolen diamonds, but the liftoff is underway before he can apprehend the criminal. When meteors collide with the ship, Astro escapes in a damaged space raft with Louie, a little girl named Marvel, Radio Announcer 'Stark' Raving, socialite Mona Toujour and crooked insurance magnate 'Rocco' Gibraltor. They land on a strange asteroid which is a frozen vacuum by night, but has breathable air by day.
