The Three Musketeers

D'Artagnan, a young country bumpkin, arrives in Paris with aspirations of becoming a king's musketeer. He carries a letter from his father introducing him to Captain Treville, commander of the King's musketeers, along with a secret sword thrust and some money.

Upon entering the city, D'Artagnan encounters the Comte De Rochefort, an agent of Cardinal Richelieu. In a scuffle, he is insulted, knocked out, and robbed of his money, which causes him to break his father's sword in the process.

D'Artagnan reaches the barracks of the King's Musketeers where he meets Captain Treville. Treville, realizing D'Artagnan is inexperienced due to his broken sword, advises him to gain combat experience before returning.

Unbeknownst to D'Artagnan, he inadvertently insults three musketeers: Athos, Porthos, and Aramis. Each challenges him to a duel in succession, leading to a series of confrontations as he tries to prove himself.

As D'Artagnan prepares for the duel with Athos, they are interrupted by Jussac and five of Cardinal Richelieu's swordsmen. A brawl ensues, and D'Artagnan joins forces with the musketeers to fend off the guards, solidifying his allegiance.

After the skirmish, Athos shares the Musketeers' motto of 'One for all, and all for one' with D'Artagnan. To assist him, Athos also shares his winnings from the guards to help D'Artagnan settle in Paris.

D'Artagnan becomes romantically involved with Constance Bonacieux, the wife of his landlord and a dressmaker for the Queen. Despite the shabby conditions of his lodging, his attraction to Constance deepens as they begin a passionate affair.

Richelieu learns of the Duke of Buckingham’s presence in France and informs King Louis XIII. Despite knowing that the Duke desires the Queen, Richelieu argues against his arrest without substantial evidence.

Cardinal Richelieu's agent, Rochefort, attacks Constance and her husband in their home, prompting Constance to seek D'Artagnan's help. D'Artagnan comforts her, and their bond grows stronger amid the danger.

Constance helps the Duke of Buckingham covertly meet the Queen, despite the risks involved. D'Artagnan, fueled by jealousy, confronts Constance about her betrayals but eventually learns the truth about their intentions.

Realizing that the Cardinal knows about her secret meetings, the Queen decides to end her relationship with Buckingham. She gifts the Duke a diamond necklace for remembrance, setting off a series of events that endanger her and Buckingham's safety.

After learning of an attack planned by Richelieu, D'Artagnan and the musketeers come to Buckingham's aid during a confrontation. This heroic act helps the Duke escape and maintain his connection with the Queen.

Constance asks D'Artagnan to travel to England to recover the lost diamonds from the Duke. D'Artagnan sets out with the musketeers but faces an ambush from the Cardinal's men, leading to a perilous journey.

After successfully retrieving the diamonds, D'Artagnan races back to Paris with only his servant remaining. They arrive just in time to deliver the necklace to the Queen, averting a royal scandal.

D'Artagnan finally proves himself to Captain Treville and is inducted into the Musketeers of the King's Guard. His achievements solidify his place among the musketeers, and he shares a significant moment of promise with Constance.
