Having read countless chivalric romances, Don Quixote decides to set out into the world to fight evil and injustice. He dreams of dedicating all his heroic deeds to his beloved lady, Dulcinea. He chooses as his squire the loyal Sancho Panza, a practical and down-to-earth peasant.

A festive holiday fills the streets of Barcelona as the townspeople welcome a famous toreador. Kitri, the innkeeper’s daughter, flirts with Basilio, the barber she loves. When Kitri’s father, Lorenzo, sees them together, he angrily drives Basilio away, intent on marrying his daughter to the wealthy nobleman Gamache. Kitri, however, firmly refuses to obey her father’s wishes.

The celebration is in full swing, when Don Quixote arrives in the square accompanied by his squire, Sancho Panza. Mistaking the innkeeper for the lord of a knight’s castle, Don Quixote greets him with great respect. Lorenzo responds kindly and invites Don Quixote to his tavern, while Sancho Panza remains in the square. The young people laugh at him, and Don Quixote hastens to defend his squire.

At that moment, Don Quixote notices Kitri and takes her for the beautiful Dulcinea of his dreams. He approaches her, but Kitri has already fled with Basilio. Don Quixote sets out in search of her.

Scene one

Kitri and Basilio are enjoying themselves in a lively tavern, where everyone dances and celebrates. Lorenzo, Gamache, Don Quixote, and Sancho Panza enter. The innkeeper insists that Kitri and Gamache be married at once.

Basilio, having agreed on the plan in advance with Kitri, stages a mock suicide. The girl pretends to weep over the body of her beloved. Filled with noble indignation, Don Quixote threatens Lorenzo with his sword and forces him to consent to his daughter’s marriage to the “dying” barber.

The innkeeper blesses the lovers, and Basilio no longer needs to feign death.

Scene Two

In a clearing near the towering windmills, a lively gypsy camp has been set up. Exhausted from their journey, Don Quixote and Sancho Panza stumble upon it. An old gypsy, with a hint of mystery, convinces the knight that he has arrived at an enchanted castle and warmly invites him in. Amidst the campfires, a young gypsy girl recounts the sorrow of her unfulfilled love, and Don Quixote, deeply moved, pledges to protect her. Spotting the windmills looming in the distance, he imagines them as malevolent sorcerers and bravely rushes into battle.

Scene Three

Exhausted, Don Quixote and Sancho Panza wander into a dense forest. The knight becomes convinced that the woods are teeming with monsters and giants. Overcome by fatigue, he falls asleep and dreams of Dulcinea, “the lady of his heart,” surrounded by graceful dryads.

Meanwhile, Sancho Panza hurries to the city to summon reinforcements for the battle against the “giants” and “sorcerers” – Lorenzo and his wife. After aiding Don Quixote, the couple warmly invites him to the wedding of Kitri and Basilio.

A lively square in Barcelona buzzes with excitement as everyone prepares for the wedding. A solemn procession moves through the crowd, and the parents bless the young couple. Don Quixote joyfully joins their hands, and the celebration reaches its peak.

And Don Quixote? Having accomplished noble deeds, he is already dreaming of new adventures – after all, there will always be someone to perform daring feats!
