Act I
The ballet opens on a sunny autumnal morning in the Rhineland during the Middle Ages. The grape harvest is in progress. Duke Albrecht of Silesia, a young nobleman, has fallen in love with a shy, beautiful peasant girl, Giselle, despite being betrothed to Bathilde, the daughter of the Duke of Courland. Albrecht disguises himself as a humble villager called "Loys" in order to court the enchanting and innocent Giselle, who knows nothing of his true identity. With the help of his squire, Albrecht hides his fine attire, hunting horn, and sword before coaxing Giselle out of her house to romance her as the harvest festivities begin.
Hilarion, a local gamekeeper, is also in love with Giselle and is highly suspicious of the newcomer who has won Giselle's affections. He tries to convince the naive Giselle that her beau cannot be trusted, but she ignores his warnings. Giselle's mother, Berthe, is very protective of her daughter, as Giselle has a weak heart that leaves her in delicate health. She discourages a relationship between Giselle and Loys, thinking Hilarion would be a better match, and disapproves of Giselle's fondness for dancing, due to the strain on her heart.
A party of noblemen seeking refreshment following the rigors of the hunt arrive in the village, Albrecht's betrothed, Bathilde, among them. Albrecht hurries away, knowing he would be recognized and greeted by Bathilde, exposing him as a nobleman. The villagers welcome the party, offer them drinks, and perform several dances.[2][3] Bathilde is charmed with Giselle's sweet and demure nature, not knowing of her relationship with Albrecht. Giselle is honored when the beautiful and regal stranger offers her a necklace as a gift before the group of nobles depart.
The villagers continue the harvest festivities, and Albrecht emerges again to dance with Giselle, who is named the Harvest Queen. Hilarion interrupts the festivities. He has discovered Albrecht's finely made sword and presents it as proof that the lovesick peasant boy is really a nobleman who is promised to another woman. Using Albrecht's hunting horn, Hilarion calls back the party of noblemen. Albrecht has no time to hide and has no choice but to greet Bathilde as his betrothed. All are shocked by the revelation, but none more than Giselle, who becomes inconsolable when faced with her lover's deception. Knowing that they can never be together, Giselle flies into a mad fit of grief in which all the tender moments she shared with "Loys" flash before her eyes. She begins to dance wildly and erratically, ultimately causing her weak heart to give out. She collapses before dying in Albrecht's arms. Hilarion and Albrecht turn on each other in rage before Albrecht flees the scene in misery. The curtain closes as Berthe weeps over her daughter's body.
In the original version, taken up again recently by a production of the ROB, Giselle stabs herself with Albrecht's sword, which explains why her body is laid to rest in the forest, in unhallowed ground, where the Wilis have the power to summon her. Most modern versions are sanitized and have edited out the suicide.
Act II
Late at night, Hilarion mourns at Giselle's forest grave, but is frightened away by the arrival of the Wilis, the ghostly spirits of maidens betrayed by their lovers. Many Wili were abandoned on their wedding days, and all died of broken hearts. The Wilis, led by their merciless queen Myrtha, dance and haunt the forest at night to exact their revenge on any man they encounter, regardless of who he may be, forcing their victims to dance until they die of exhaustion.
Myrtha and the Wilis rouse Giselle's spirit from her grave and induct her into their clan before disappearing into the forest. Albrecht arrives to lay flowers on Giselle's grave and he weeps with guilt over her death. Giselle's spirit appears and Albrecht begs her forgiveness. Giselle, her love undiminished unlike her vengeful sisters, gently forgives him. She disappears to join the rest of the Wilis and Albrecht desperately follows her.
Meanwhile, the Wilis have cornered a terrified Hilarion. They use their magic to force him to dance until he is nearly dead, and then drown him in a nearby lake. Then they spy Albrecht, and turn on him, sentencing him to death as well. He pleads to Myrtha for his life, but she coldly refuses. Giselle's pleas are also dismissed and Albrecht is forced to dance until sunrise. However, the power of Giselle's love counters the Wilis' magic and spares his life. The other spirits return to their graves at daybreak, but Giselle has broken through the chains of hatred and vengeance that control the Wilis, and is thus released from their powers and will haunt the forest no longer. After bidding a tender farewell to Albrecht, Giselle returns to her grave to rest in peace.

Prologue
Don Quixote's Study
Bachelor Sanson Carrasco is seen covering a bookcase with wallpaper, while Antonina is putting some rusty old armour and a helmet made of pasteboard into a cupboard. Don Quixote de la Mancha enters, reading a book. He goes to the bookcase and, not finding it, believes it has been stolen by evil magicians. Then he settles into an armchair and continues reading. He delights in stories of brave knights, fabulous giants and other fantastical creatures, but most of all Don Quixote dreams of his beloved Dulcinea, a woman that he believes to be so lovely and noble that she must be divinity. Gradually he nods and falls asleep to dream of their romantic adventures. Darkness falls.
Suddenly his servant, Sancho Panza, climbs hurriedly through the window. In pursuit are several angry women from the market from whom he has stolen bread and a chicken. Awakened by the commotion, Don Quixote sends the women away. Don Quixote tells Sancho that he is determined to seek adventures as a knight-errant, all the while searching for his beloved Dulcinea. He shows him the pasteboard helmet, which, with one sweep from his sword, becomes a shapeless mass on the floor. Antonina suggests that he should use a shaving basin instead, which would make a splendid helmet. Don Quixote enthusiastically agrees and, placing it on his head, orders Sancho to bring him his armour, sword and spear, and to make ready his horse, Rocinante.
Act I
A market-place in Barcelona
Kitri, an inn-keeper's daughter, steals out of her house to meet her beloved, the barber Basilio. Her father, Lorenzo, sees the lovers and sends Basilio away, bringing Kitri to tears. Now comes the rich nobleman Gamache, who, likewise in love with Kitri, goes to Lorenzo and asks for his daughter's hand. The innkeeper accepts with delight but Kitri, appalled at the thought of wedding the foppish nobleman, runs away.
Dancing begins in the square and some toreadors try to kidnap the girls they fancy, but their relatives and lovers hasten to their aid. At this moment Don Quixote arrives mounted on Rocinante, followed by Sancho, who is riding a donkey. At his master's command Sancho sounds his rusted horn, causing the townspeople to cover their ears. Lorenzo runs out of his inn, and Don Quixote, taking him for the lord of a famous castle, dismounts Rocinante and, falling to his knees, begs to be allowed to serve him. Charmed, Lorenzo invites the knight to sit on his balcony. Sancho remains in the square where he is surrounded by girls who induce him to take part in a game of blind man's bluff. Then some boys bring in a blanket on which they place Sancho and proceed to toss him into the air. Don Quixote hurries to his assistance and sets him free.
Peasants gather in the square and dancing resumes. Kitri returns and, noticing her, Don Quixote acclaims her as his Dulcinea, whom evil magicians have reduced to human form. Becoming jealous of her affection for Basilio, Don Quixote attempts to woo her by partnering her in a minuet. Lorenzo berates Kitri for carrying on with Basilio. Kitri and Basilio then run away, and Lorenzo and Gamache follow them. Don Quixote orders Sancho to bring Rocinante, so that he may also set out in pursuit.
Act II
Scene 1 – A camp of gypsies among the windmills outside the village
Kitri, disguised as a boy is seen walking with Harlequin from a troupe of travelling actors. They guess she is a girl and ask her to stay with them.
Scene 2 - The Puppet Theatre
A clown is seen walking with Graziosa, the gypsy chief's daughter. A gypsy tells the chief of the approach of Don Quixote. The chief plans a trick for his benefit and, putting on a mantle crown, sits down as though he were a king on a throne. Don Quixote is deceived and kneels to the chief in homage. The chief bids that he sit beside him and orders a festival to be given in his honor. This begins with Gypsy dances and is followed by a performance of the marionette theatre. Don Quixote is delighted with the entertainment but, mistaking the heroine for his Dulcinea and the marionettes for soldiers attacking her, he rises to assault them. The gypsies are terrified. At this moment the clown and Graziosa run away.
Scene 3 - The Windmills
Flushed with victory, the knight kneels and renders thanks to heaven. Seeing the moon, he takes it for his Dulcinea and tries to get to her. As he approaches the windmills he can see the moon no longer and thinks that evil magicians have hidden his beloved mistress. So, spear in hand, he tilts at the wings of the windmill, which he mistakes for a giant. Alas, the knight is caught by one of the wings and flung into the air. He falls unconscious at Sancho's feet.
Scene 4 – A forest
Through the trees appears Sancho leading Rocinante, upon which sits the wounded Don Quixote. The servant lifts his master down and places him on the grass, so that he may rest. Then, tying up the horse, he goes to sleep. Don Quixote also tries to sleep, but is troubled by fantastic dreams.
Scene 5 – The enchanted Garden of Dulcinea
Fairies appear surrounded by gnomes and Don Quixote finds himself dressed in shining armor. Then comes a succession of fearsome monsters, the last being a gigantic spider, who spins a web. The knight attacks the spider, which he slashes in half with his sword. At that same moment the spider's web vanishes to reveal a beautiful garden, filled with dryads and beautiful women, presided over by the Queen of the Dryads and Amor. Among them is Dulcinea and Don Quixote kneels before his beloved. At this moment everything vanishes.
Act III
The Square
Back at the square, Kitri and Basilio join those who are dancing. At the height of the merriment, Lorenzo and Gamache arrive, followed by Don Quixote and Sancho. Seeing his daughter, Lorenzo decides to give his blessing to her union with the nobleman Gamache. Basilio becomes annoyed and, reproaching Kitri for her unfaithfulness, draws a sword and stabs himself. As he lies dying he begs Lorenzo to unite him with Kitri, but Lorenzo and Gamache refuse. Don Quixote approaches Gamache and challenges him to a duel for having refused a dying man's wish. Gamache declines to fight and the merrymakers drive him out of the inn. Taking pity, Lorenzo agrees to unite Basilio and Kitri. At this moment, Basilio pulls out the sword and tells everyone it was a joke.
Act IV
The Tavern
A magnificent feast is held in honour of Don Quixote. Suddenly the Knight of the Silver Moon challenges him to a duel, which results in the latter being vanquished. The victorious knight proves to be none other than Bachelor Sanson Carrasco, who forces Don Quixote to vow that he will not unsheathe his sword for a whole year. The sorrowful knight, true to his vow, takes up his warlike gear and, followed by Sancho, sets out for home.
