The document provides a detailed plot analysis of a music video for the song "Castle" by Halsey. It summarizes: The video tells the story of a young, benevolent princess who wants to reclaim power in her kingdom from a tyrannical prince's family. She initially believes she can peacefully take the throne but discovers this is not possible. This causes her to snap and violently overthrow the prince to gain power herself, becoming corrupted by it in the process. The video shows the princess devolve from peaceful to aggressive as she strips the prince of his royal garments and crown, reversing their roles.
