Barbie and the Three Musketeers

Corinne, a seventeen-year-old girl living on a farm in 17th-century France, aspires to become a Musketeer like her father, D'Artagnan. She dreams of joining the legendary fighters in Paris despite her modest background. Her kitten Miette shares the same dream of becoming a 'mus-cat-eer'.

Corinne and Miette arrive in Paris, where she faces ridicule from others, especially Prince Philippe. Her letter to Monsieur Treville is stolen by Philippe's dog, Brutus, causing her to struggle to make a good impression. Despite setbacks, she remains determined to prove herself.

After a series of mishaps, Corinne is hired as a palace maid by Madame de Bosse, along with her friends Viveca, Aramina, and Renee. They face initial hardship but are helped by each other and make new friends amidst the palace life.

Corinne encounters Prince Louis for the first time during her work at the palace. During a ball, a chandelier nearly falls on Louis, but Corinne, along with her friends, defends themselves from falling debris. A mysterious gem is found near the chandelier's cut rope.

Corinne and her friends overhear Helen, an old maid, talking about the musketeers and are led through a secret passage to an old musketeer's training room. Helen agrees to train them to become true musketeers.

While cleaning, Corinne spots Louis hanging from his hot-air balloon and rescues him just in time. They share a moment, and Louis thanks her. Corinne notices the same cut rope issue, making her suspicious of foul play.

Corinne and her friends complete their musketeer training with Helen. They decide to celebrate their skills, but soon uncover a plot to assassinate Prince Louis at the upcoming masquerade ball involving weapons smuggled by Regent's men.

The girls sneak into the masquerade ball disguised in masks to warn Louis about the assassination plot. Louis dances with Corinne, not knowing her true identity, as the villains attack and capture Treville and the musketeers.

Corinne and her friends fight the villains, rescue Prince Louis, and chase the antagonists—Phillippe, Regent, Brutus, and their men—to the rooftops. Corinne's quick thinking helps save the prince and thwart the evil plan.

After defeating the villains, Corinne and her friends reveal their true identities. Louis is crowned king, and the girls are named royal musketeers. Corinne's motherhood pride is fulfilled as she achieves her dream.

With peace restored, Helen takes Madame de Bosse’s place as a maid, and Corinne, Viveca, Aramina, and Renee prepare for more adventures. Louis offers to take Corinne on another balloon ride, but she is called away by a new threat, signaling more heroism ahead.
