The film opens with the famous singer and actor Yves Montand arriving in Marseille, where he grew up, to rehearse a new musical based on his life. From his years as an unknown, including the loss of his first great love, the show moves on to his artistic and amorous links with great stars like
Édith Piaf and
Marilyn Monroe. In his free time, he looks up old friends, hoping in particular to find Mylène, his first love who worked as a prostitute. At his hotel, a card is left by Baroness de Lambert, who asks to see him. While in his dressing room, he is entranced by a fan called Marion, who asks him for three seats on the 26th so that she and the two girls she works with can attend the sold-out opening night. Though trained in acting, song and dance, she works in a perfume shop. When the leading lady has to leave the cast because of pregnancy, Marion volunteers and is hired. When Yves rings up the mysterious baroness, he recognises from her voice that she is Mylène and the two have a tender reunion in the bar where they first met. She is living with the daughter she had after they parted but will lose her home as her husband has been sent to prison for five years. The opening is a great success, and the show is booked to run in Paris. Marion spends the night with Yves and, as they talk about each other's lives over breakfast, she realises that she is his daughter. Unshaken in her love for him, she goes home to get her mother. The two women he has loved most in his life then join Yves on the train to Paris. == Cast ==
