The Swan Princess: Royally Undercover

In the middle of the night a strange masked man goes to the kingdom of Trumbeau. There, he makes a huge hole underneath a dam near the village where everybody is fast asleep and disappears. The next morning Derek, Odette and Chef Ferdinand are going to the village to have a trade agreement meeting. The Trumbeau's king and his wife were friends of King William, Odette's late father. King William once saved his life and Odette mentioned that her father often had told her about that.
