This film has a prince and a dragon, but it is definitely not a fairy tale. Princess Elodie (Millie Bobby Brown) agrees to marry the handsome Prince Henry, but is shocked to find that the royal family intends to sacrifice her to a dragon to repay an ancient debt passed down from generation to generation in the family. She is mercilessly thrown into a cave as a sacrifice. Facing the savage, fire-breathing dragon, she must rely on courage and wisdom to escape.
