Three days in the lives of six friends who are nearly 30 years old, live in Grenoble, and have a rock band called the Why Notes?. Theyre to play in Paris at Charless school reunion. In getting to Paris and back, the characters interact with Aimees ex-husband and her abrasive, cruel ex-mentor, Louises would-be lover who turns out to have a husband, Mickeys long-time lover and her children, Bertrands Germanic wife and their children who speak no French, and Frederics distant mother. The band also meets Clara, a mercurial free spirit who beguiles Bertrand, then Mickey, then takes up with someone else in the band.
