Julia, a young director of the Public Theatre in Barcelona, decides to take on an ambitious project: a play about Madame de Sevigne (1626-96). The Parisian marchioness was famous for a collection of 1700 letters to her daughter. Julia must choose between her conventional life with her husband, Gerardo, an influential theater critic, and Ignasi, the attractive programmer at the theatre with whom she is having an affair — or a fresh new start with the author and female lead of the play.
