At dawn at the Barrière d’Enfer, a toll-gate on the edge of Paris, a customs official admits farm women to the city. Guests are heard drinking and singing within a tavern. Mimì arrives, searching for the place where Marcello and Musetta now live. When the painter appears, she tells him of her distress over Rodolfo’s incessant jealousy. She says she believes it is best that they part. As Rodolfo emerges from the tavern, Mimì hides nearby. Rodolfo tells Marcello that he wants to separate from Mimì, blaming her flirtatiousness. Pressed for the real reason, he breaks down, saying that her illness can only grow worse in the poverty they share. Overcome with emotion, Mimì comes forward to say goodbye to her lover. Marcello runs back into the tavern upon hearing Musetta’s laughter. While Mimì and Rodolfo recall past happiness, Marcello returns with Musetta, quarreling about her flirting with a customer. They hurl insults at each other and part, but Mimì and Rodolfo decide to remain together until springtime.
