The little dragon Coconut, the porcupine Matilda, and the hungry dragon Oskar are quite astonished when a space glider with a small alien lands right in front of them on the beach of Dragon Island. The visitor from outer space has hopelessly lost his way on his first solo flight, and now he can't get his space glider to start. Coconut and his friends promise to help the stranded alien and accompany him back home. In the process, the three friends find themselves in another exciting adventure, this time set in the vastness of space.
