On a little island lives Ferdi, a little boy stonefly with his parents. Stoneflies cannot fly, they are too heavy and their wings cannot carry them. But Ferdi's biggest wish is to fly. So he sets off on a journey to learn how to fly. On his way he meets several stones which he asks about the art of flying, but none of them is really able to help him. When he has already given up all hope and accepts his fate, he meets a little girl - and his dream comes true.
