When Garance learns of her grandfather's illness, she suddenly realizes how little she knows about him, especially about his youth and what led him so far from his home country, Cambodia.
Trying to make up for lost time, she starts visiting him as often as she can to talk to him about his past. Little does she suspect the impact the old man's story will have on own life and her relationship with her parents. She eventually finds out that her grandfather had another wife and two children in Cambodia, who all died in the Khmer labor camps. She sets out on a trip to the Cambodian countryside to find out more.
