Act I
Rodolfo and Marcello shiver in their attic, burning the poet’s manuscript for warmth. Colline arrives empty-handed—pawnshops are closed—but Schaunard bursts in with money and a feast. After a joyful meal and outwitting the landlord, the friends head to the café. Rodolfo lingers to write, but a gentle knock interrupts: Mimì, her candle snuffed out by the wind. In the soft glow of moonlight, two hearts draw close, and love quietly takes root.
Act II
As the festive crowd swirls through the streets, the four friends and Mimì celebrate Christmas Eve at Café Momus. Musetta arrives with her wealthy companion, Alcindoro, but her sights are set on rekindling love with Marcello. With playful cunning, she ditches the old admirer and reunites with the painter. When the bohemians slip away, Alcindoro returns to find only the unpaid bill.
Act III
At dawn, in the cold fog near Barrière d’Enfer, Mimì seeks out Marcello at the tavern where he lives with Musetta. She confides that Rodolfo’s jealousy is driving them apart, though they still love each other deeply. Marcello offers to help. Hiding nearby, Mimì overhears Rodolfo confess to Marcello that he still loves her, but she is gravely ill, and he believes she’d be better off with someone who can care for her. Her sobs give her away. Reunited in tears, Mimì and Rodolfo vow to stay together until spring, as Musetta and Marcello slip back into a quarrel.
Act IV
In the attic once more, Rodolfo and Marcello try to work, but memories of Mimì and Musetta cloud their thoughts. Colline and Schaunard arrive, lifting the mood—until Musetta bursts in with grave news: Mimì is on her way, too weak to go on, longing to die where she was once happy. Left alone, the lovers tenderly recall their first meeting. One by one, the others return. As Colline gently closes the door, Mimì slips away quietly, forever.
