The refugee camp Khao-I-Dang on the border of Cambodia and Thailand was known as the “hill of death.” Hundreds of thousands of people fleeing famine or certain death under the Khmer Rouge arrived there exhausted. Among them were a mother and her baby daughter, who later found a home in France. Fourty years later, the daughter—filmmaker Neary Adeline Hay—follows the trail back in a highly personal, elegantly filmed journey through their past.
