Forced out of their forest home by the construction of an airplane factory, Gus and his fellow Gremlins set out to sabotage the British Royal Air Force's planes in revenge. But after meeting a pilot also named Gus and explaining the plight of his people, they strike a deal: Gremlin Gus will reform the Gremlins and now assist in the upkeep of planes in exchange for free food (in the form of postage stamps) and an untouched forest being set aside for the Gremlins to live in. When the pilot Gus is shot down and injured, the Gremlins help in his recovery and help him pass a medical exam later on in his recovery, allowing him to take to the skies again.
