In 1662, the
Kingdom of France moves toward revolution, facing bankruptcy from King
Louis XIV's wars against
the Dutch. The young and callous King Louis redistributes spoiled food supplies from the army to his starving citizens, and instructs former Musketeer
Aramis to find and kill the unknown leader of the renegade
Jesuits seeking to assassinate the king. At a palace festival, Louis attempts to seduce Christine Bellefort, the fiancée of Raoul, son of former Musketeer
Athos, while
D'Artagnan, captain of the king's guard, foils a Jesuit assassin. Sending Raoul to his death on the battlefront, Louis takes Christine as his mistress, and Athos renounces his allegiance to the king. When D'Artagnan defuses a riot over the rotten food supplies, Louis orders his chief advisor to be executed and future rioters to be shot. Aramis summons Athos, D'Artagnan and former Musketeer
Porthos for a secret meeting, revealing himself as the Jesuits' leader with a plan to depose Louis, but D'Artagnan refuses to join them. Athos, Porthos and Aramis infiltrate the
Île Sainte-Marguerite prison and free a prisoner wearing an iron mask, whom Aramis reveals to be Philippe, Louis's identical twin brother. To avoid dynastic warfare when
Queen Anne gave birth to twins, King
Louis XIII sent Philippe to be raised in the country without knowledge of his true identity, telling the queen that the child had died. On his deathbed, the king informed his wife and son of Philippe's existence; fearful of losing his throne, Louis XIV forced Aramis to seal Philippe in the iron mask and imprison him for life. Wishing to redeem himself and save France, Aramis informs Anne of his plan to replace the cruel Louis with the benevolent Philippe. With mere weeks to tutor Philippe in courtly life, Athos, Porthos and Aramis subdue Louis during a masquerade ball at the palace, as Philippe assumes his brother's identity and returns to the festivities. Christine publicly confronts the king for his role in Raoul's death, and D'Artagnan realizes the ruse when Philippe treats her with kindness, in stark contrast to the heartless Louis. D'Artagnan and his men intercept Athos, Porthos and Aramis in the dungeons, rescuing Louis as the trio escape, but Philippe is captured. After learning Philippe's identity, D'Artagnan begs Louis to spare his brother, and Louis returns Philippe to prison in the iron mask, while Christine hangs herself. D'Artagnan summons Athos, Porthos and Aramis to help rescue Philippe from the
Bastille, where they are ambushed by Louis, who offers D'Artagnan clemency in exchange for his surrender. D'Artagnan refuses, revealing to his comrades that he is Louis and Philippe's biological father, having long been in love with Anne. The four former Musketeers charge as the king's guards open fire, but their bravery compels the soldiers to deliberately miss. Shielding Philippe from Louis, D'Artagnan is fatally stabbed, while his protégé Lieutenant André turns against Louis, as Philippe again takes his brother's place as king. Philippe ascends to the throne under Louis's identity, naming Athos, Porthos and Aramis as his closest advisors and holding a funeral for D'Artagnan. Rumored to have issued his brother a royal pardon, permitting Louis to live out the remainder of his life in peace, Philippe ultimately becomes one of France's greatest kings. ==Cast==
