The Legend of Prince Valiant

The kingdom of Thule has fallen under the attack of King Sinnin and his massive army. The forces of King Willam manage to hold out until their ruler drops his guard during the battle. Sinnin wins the day and forces the survivors, including young Prince Valiant, to sail to a primitive land far from their home. But Valiant eventually learns that Destiny does not intend for him to wallow in exile for long.
