Christopher appears to be an everyday 10-year-old boy, but he's actually an alien, or perhaps a mutant. The FBI isn't exactly sure what he is, but they're looking for him and his family in any case. His mother, meanwhile, surrounded by extraordinarily powerful and advanced communications equipment, runs their home with an iron fist. When Christopher begins telling stories in school about Shakespeare being a transvestite and the dinosaurs being wiped out by ESP—stories he can back up with an incredible amount of detail—Mother cracks down immediately. Christopher, she rules, is to be "scooped out," neutralized, turned into a pale shadow of himself. Determined to escape his punishment, the boy, aided by his grandfather and a time machine disguised as a bathroom, sets off on a bizarre and painfully humorous adventure through multiple universes.
