A man dressed in fiery red announces to the whole universe that Rainbow Sea, a place of precious stones, golden rivers and rainbow skies where every wish comes true, lies at the heart of a black hole. Crowds follow him inside, and none of them return. He becomes known as the Red Devil, and Rainbow Sea is written off as the greatest lie in history. Ten years later, his son Maidang, a teenager raised on Earth, sets out to find Rainbow Sea and keep a promise he made to his father. A rainbow stone left behind by his dad gives him a strange power: he fights with cooking techniques. He wrecks the no-fly facility that the Evil Galactic Eye organization built on Earth, and along the way he is joined by Gudong, an odd rabbit who insists he is a king. The result is a short-format mix of adventure, fantasy and science fiction.
