This French-language film is loosely based on Marcel Proust's novel La Prisonnière.

[1] Simon (Stanislas Merhar) lives in an apartment with his grandmother and his girlfriend Ariane (Sylvie Testud).

Simon begins to grow jealous of Ariane's friends and suspects that she is having an affair with another woman.

Ariane agrees to leave Simon and he drives her to her aunt's house where she plans to move.

When they arrive at Ariane's aunt's home Simon finds himself unable to leave her there and begs her to come back.
