On the grand sweep of the Pigdom Plains lives a small pig called Lily, the daughter of renowned inventor, Hercules Fatchops. Hercules' personal holy grail is to invent powered aircraft, a feat already achieved in secret by Lily. Hercules prizes only science, but Lily's innovations employ science and magic. She will need both, because now the Pigdom faces invasion from terrifying adversaries with more advanced aircraft - from over the mountains come the warthogs, intent on destroying the Pigdom.
