Annie (Anouk Aimei Anouk Aimee) and Joan (Jean Louis Trantinion Jean-Louis Trintignant) used to be lovers who loved each other very much, but their love failed to blossom because of fate, and the two ended up going their separate ways. Fifty years later, the aging Joan was suffering from Alzheimer's disease, so severe that he didn't even know his own daughter. The only person Joan KAOS remembers in her brain is Annie. In order to alleviate his father's illness, Joan's son Anthony (Antoine Sire) tries to get in touch with Anne in the hope that she can come and see his father in order to solve the pain of missing his father. Who knew that Anne was also unable to let go of the relationship she had had. As soon as the two met, the feelings that had been repressed in their hearts for many years revived.
