A mysterious young woman weeps by a fountain in a forest over a lost crown. Prince Golaud stumbles upon her while out hunting, and events are set into motion. Debussy’s impressionist score to Maeterlinck’s symbolist play builds up atmospheric musical scenery.
The young woman by the fountain is named Mélisande. She will not tell Golaud anything more about who she is, but agrees to come with him.
A letter arrives for Golaud’s parents, Geneviève and King Arkel. We find out that the widowed Golaud has married Mélisande rather than the Princess Ursule, with whom he could have formed an advantageous political match. Despite the implications of his recklessness, Golaud’s parents accept their son’s decision.
Golaud has a younger brother, Prince Pelléas. Pelléas decides to set off and visit a friend who is on his deathbed, but agrees to stay longer to wait for Golaud to come home with his bride. Later, Geneviève and Mélisande are walking together in a garden. After Geneviève leaves to take care of Golaud’s son Yniold, Pelléas begins to make subtle romantic overtures toward Mélisande.
This romance blossoms in the second act. Mélisande plays with her ring while sitting with Pelléas by the Blind Man’s Well. Her ring falls in the water as the clock strikes twelve, and we find out that at that exact moment, Golaud had an accident that has left him wounded.
When Mélisande is at her new husband’s bedside, Golaud notices that her ring is missing, but she lies that she lost it in a cave by the sea. Golaud sends her off to look for it even though night has fallen, and sends Pelléas to accompany her.
In the third act, Mélisande brushes her long hair in a Rapunzel-like vignette as Pelléas caresses it. Golaud becomes suspicious of the couple and forces his little son Yniold to spy on them. The child admits he saw Pelléas and Mélisande kiss, but is frightfully harassed by his emotionally charged father.
Symbols abound in the fourth act: Golaud appears with blood on his forehead and confronts Mélisande about her spending time with Pelléas. Yniold loses his golden ball and a flock of sheep suddenly fall silent and stop bleating. Pelléas and Mélisande finally confess their deep love for one another by the Blind Man’s Well where she lost the ring. By the well, Golaud confronts the lover and strikes Pelléas dead with a sword.
In the fifth act, the ultimate tragedy ties the narrative together: Mélisande dies shortly after giving birth, and in her last moments she denies her love for Pelléas to Golaud, insisting that she is telling the truth.
