Forty years ago, the Khmer Rouge sought to break up the bond of the family.
Today, through a television show called "It's not a dream", members of different families are reunited, while watched by millions across Cambodia.
The production staff searches for missing family members based on information people send in after watching the show.
Over 2,000 people have sent in applications, hoping for a reunion of their own.
