After being sent to live with his grandmother in Orange Farm, a poor township outside Johannesburg, Jimmy has strange nightmares in three consecutive nights. On the forth night, however, his nightmare continues even after he has awakened, as he hears strange sounds of heavy wing flapping outside. Shortly, there is a knock on the door, and his name is called out. It turns out to be eleven enormous greenflies, who tell him that they are from Sisiva, and that they have come to invite Jimmy to their country, where a prophecy says he must succeed their recently died emperor as new emperor. But upon travelling with them, Jimmy discovers that the greenflies are deceiving him. Their real intention is to ceremonially kill, cook and eat him so as to regain their long lost wisdom, and revive the Golden age of Sisiva during which Sisiva was the most technologically advanced territory in the cosmos, and greenflies ruled as the most skilled creatures.
