In a very small house, on a very high mountain live three people: a mother, her little daughter and an older son. One day the girl goes outside to play with her kite. It is very windy and cloudy. The girl goes too far away from their house but she has a lot of fun and she doesn't see that a bad dragon comes in her direction. The dragon catches her. The girl screams but nobody can hear her. The dragon flies away with the girl.
At the same time her older brother, who is working in the garden, sees a dragon with his sister on the sky. He calls their mother but they can do nothing. The boy decides to go and look for his little sister. He goes to a wizard for help. The wizard gives him the map where the dragon lives and a fast black horse to go quickly to save his sister.
He rides his horse through a big forest when suddenly bad goblins surround him and don't let him go farther. He decides to give them all his money and the horse. They agree to let him go. He walks through the forest without his horse and he is very tired. Finally he gets to the dragon's castle.
He enters the castle and he can hear a loud noise. This is the dragon which is sleeping. He goes from one room to another and he finds his sister in one of them. In the end he takes his sister and they go home together.
