Julie and her boyfriend Ismaël are living together. Rather than worry about the time he spends with his colleague Alice, Julie invites Alice to join them. The three walk the streets of Paris, party, read, and sleep together. Sometimes it's lighthearted, sometimes there are jealousies. Then death strikes. In various ways, those left behind come to terms with the departure and absence of a loved one: showing concern, attempting new relationships. The romantic elements of musical comedy play in contrast to the ambivalence of the lyrics and the story.
