This is the story of a young boy, named after a licence plate, and his sister, named after a type of floor polish who battle an alien menace, the void of space, scary things in sewers and massive explosions, all while discussing the psychologically paradoxical nature of evil, the universe and everything else.

They are aided in their quest by Bopi, a cyborg posing as the family pet, Madame Esmeralda- a small medium, a welsh self taught astronaut in a home made suit, a computer with a head-cold and a thermonuclear bomb who is afraid to die.

Cameo appearances from the men in almost black, killer robots with faulty logic circuits, a horde of giant slavering monsters, cyborgs and succubi as well as countless sci-fi in jokes and references to keep the adults amused.
