Frontiers S01E08 - Border Run

Fifteen years ago, prize-winning journalist Jon Swain was trapped in Phnom Penh, capital of Cambodia, when the Khmer Rouge took the city. A bone-crunching journey by truck eventually took him to the Thai frontier and freedom, but millions of Cambodians died in the bloodbath that followed.

Thousands of those who escaped still live in crowded camps just inside Thailand, waiting for a chance to build a new life. In tonight's film, Jon Swain returns to both sides of the frontier that has seen so much tragedy.
