At the center of this fantastical story is a little boy named Lucky. He lost his parents at a young age, and all he has left to remember them by is the name of his home planet - Regime. Getting there is not so simple, as it is hundreds of light years away from where the boy currently lives. But he decides to embark on a grand journey and secretly boards the "White Whale" - a massive interstellar liner drifting in open space. He wants to find and reclaim his world.
