 In May 1994, during the opening of the first "Sidaction", on the day against Aids, Barbara Samson, a 17-year-old girl, upsets France. She tells the public about her tragic destiny, her unhapinness, and how she has been contaminated by the virus. They are the best friends of the world. Five friends who shared everything: may 68, hippies years, the rock and their love for Bernadette. This Bernadette has left them to become a rock-star, and is back 15 years later for a weekend. Jean-Marie Poire describes with this movie the portrait of a generation with lots of humor served by excelent actors.
