On My Mother's Side(L'Origine des espèces)

David happily brings his wife and new baby to his parents to celebrate his birthday. All goes well until the next day, when he finds that his mother – a filmmaker – has committed suicide. His second shock comes on the day of the funeral, when he is told that the man who raised him is not his biological father. Bewildered, he starts to look for answers and finds a hidden side of his mother’s life.
