-Telling the big story through a little one: that was the task Charles Gervais set for himself in "La part d'ombre", his documentary. Nelly-Thidia was born in Montreal (Canada). Her parents, Cambodian refugees, escaped genocide, and their daughter grew up wondering about the horrific legacy. As the first international trial opened in Cambodia to shed light on the atrocities committed between 1975 and 1979 by the Khmer Rouge under leader Pol Pot, when an estimated 25% of the country's population perished, Nelly-Thidia decided to visit her parents' homeland in order to face down her own demons and try to understand the malaise that still afflicts her family life. Through her journey, we are exposed to the horror of a people haunted by a murderous past, whose wounds are still raw. An unsettling, moving and sensitive film.
