The Man in the Iron Mask
This animated retelling of Alexander Dumas' novel of the same name follows the legendary three musketeers -- D'Artagnan, Aramis, and Pathos, respectively -- on their journey to rescue the rightful King of France. While his tyrannical twin brother occupies the throne, the true heir has been left to rot in a dungeon, clad in rags and a cruel iron mask created to hide his identity from the people of France.
