Amid the shouts of street hawkers near the Café Momus, Rodolfo buys Mimì a bonnet and introduces her to his friends. They all sit down and order supper. Marcello’s former sweetheart, Musetta, makes a noisy entrance on the arm of the elderly, but wealthy, Alcindoro. The ensuing tumult reaches its peak when, trying to gain Marcello’s attention, she loudly sings the praises of her own popularity. Sending Alcindoro away to buy her a new pair of shoes, Musetta finally falls into Marcello’s arms. Soldiers march by the café, and as the bohemians fall in behind, the returning Alcindoro is presented with the check.
