Benjamin, a young German computer whiz, is invited to join a subversive hacker group that wants to be noticed on the world's stage.
After studying in Paris, the young doctor François moves to Beauval, where single-family houses are lined up monotonously. He quickly becomes the focus of a group of young people, led by the charismatic Cédric and Matthieu, his assistant. The gang tries to escape their boredom with dangerous games at the edge of the forest. But things become bitterly serious when the body of a twelve-year-old girl is found and François is suspected.
Born under unusual circumstances, Benjamin Button springs into being as an elderly man in a New Orleans nursing home and ages in reverse. Twelve years after his birth, he meets Daisy, a child who flits in and out of his life as she grows up to be a dancer. Though he has all sorts of unusual adventures over the course of his life, it is his relationship with Daisy, and the hope that they will come together at the right time, that drives Benjamin forward.
