This animated retelling of Alexander Dumas novel of the same name follows the legendary three musketeers -- DArtagnan, 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. ~ Tracie Cooper, All Movie Guide
