Rodin, alone in the studio-apartment he has rented for himself and Camille, is reached by his long-term companion Rose who tries forcing him to come back home, pointing out all she has done for him and that they have a son together. Rodin does not give in and Rose leaves.
Camille enters and she and Rodin begin to laugh and joke lightheartedly, humming a popular tune and stealing each other the sculpting tools. Rodin invites her to dance, but Camille has some problems because of her bad leg. Rodin makes her sit and goes out to buy something to drink. Before he can leave, Camille stops him and starts asking him questions about his new project, which she feels has not been involved with. Feeling she has been put aside, Camille gets upset with Rodin, who tries to reassure her. She cools off and Rodin finally is able to get out.
Rose suddenly enters and begins to furiously insult Camille while looking for Rodin. Rose takes one of Camille’s sculptures to throw it to the ground, Camille rushes to stop her and begins to hit her, until Rose falls down. Even when she is on the ground, Camille does not stop. Rodin comes back in and Camille stops, Rose remains still on the ground, Rodin goes and leans over her. He takes a wet cloth, uncovering one of his sculptures, and puts it on her forehead. Rose slowly opens her eyes. Rodin helps her up and they start to leave the scene. Meanwhile, Camille noticed that the bust discovered by Rodin is very similar to one of her sculptures. Camille asks for an explanation and gradually uncovers other sculptures that Rodin has copied. While Rose accuses her of plagiarism, Rodin remains impassive, suggesting that no one would ever believe that the great Rodin could copy one of his students.
Rodin and Rose are about to leave, but Camille, furious, holds them. Paul comes in. Camille tries to hurl against Rose, but Paul holds her. Rose takes Rodin away. Young Camille pounces on her sculptures and throws them to the ground, destroying them. The old Camille reappears. Paul tries to calm Camille, while old Camille hangs over her brandishing the ghost of her annihilation as an artist. Camille falls to her knees, betrayed by the great Rodin [Scene as “L’Age Mûr”.]
