Sixteen years after the end of World War II, Thérèse Langlois owns a pub in Puteaux, Paris. Wrapping up the season, she plans her annual vacation in Chaulieu with her lover, but is growing emotionally distant towards him. At the pub, a tramp walks by daily singing The Barber of Seville aria and other opera songs. Intrigued, Thérèse has her bartender Martine call the tramp in for a drink. The tramp, who says he lives by the river, reveals he is suffering from amnesia but carries identification indicating his name is Robert Landais. After the tramp leaves, Thérèse follows the tramp to the river and studies his face and movements; she becomes convinced he is in fact her long-lost husband Albert Langlois.
