Once upon a time, there was a dragon that lived in a cave full of gold. The cave was well hidden from people, whom the mighty dragon hated from the bottom of his soul. The treasure was his joy and pleasure, but he had no one to share it with. That's why he went to a witch for help. He wanted some offspring. The witch was happy to help him, but she had one condition: If he gets angry, the witch will come for his second favorite thing. The dragon agrees to this stupid condition, and he gets eggs which hatch 3 dragon offspring. One of them looks like a human girl. The dragon names her Bristle. She grows up next to her dragon siblings and enjoys the love of her dragon father, whom she loves unconditionally. When she saves the life of a princess from the castle in the forest, the dragon gets angry, the witch comes, and Bristle learns that she is the dragon’s second favorite thing. She decides to leave her father and enters the world of people, experiencing not only anger and resentment, but also friendship and solidarity.
