The fall of Phnom Penh to the Khmer Rouge in 1975 was the beginning of a genocide that would claim up to 2 million lives. Among the hundreds of thousands of Cambodians who fled the horror, many found refuge in France. But 50 years on, what remains of their memories? We take a closer look in this edition of France in Focus.

"It may seem excessive, but in a sense we died that day because everything that was true the day before changed overnight." These words by Phouséra "Séra" Ing, a Franco-Cambodian artist, resonate like a painful echo of the countless lives pierced by war, genocide and exile.

Through the testimonies of survivors and their descendants, this episode of France in Focus explores the struggles of exile and the transmission of memory. How do survivors speak of the unspeakable? How do their children grow up with a legacy of silence and things left unsaid?

From the French embassy in Phnom Penh to Thai refugee camps, from villages in rural France to the suburbs of Paris, this film traces these journeys of exile and reconstruction. We meet Séra, who found a way to heal his wounds through comic books; Sambo, who took 15 years to feel at home in France; and Virak, who discovered his father's story late in life. Each of their stories reveals the difficulty of bringing generations together to discuss a collective trauma.

As a memorial to those lost in the Cambodian genocide is unveiled in France, survivors are finally learning to speak freely and heal. Because as Sun-Lay, president of the Fragmentis Vitae Asia Association, reminds us: "Memory is the remedy for the pain of the present."
