Children of the Secret State is a documentary film about homeless North Korean orphans, released in 2000.
The movie shows the empty streets and unused fun fair and hotels, as well as the well cared-for 'children of the elite', whom he contrasts with footage of starving orphans filmed by Ahn Chol.
[2] Ahn Chol, who planned to meet up with the couple at the border, fails to turn up, but Layburn proceeds to interview refugees who have fled into China from North Korea.
[1] He also states that the factories, and most industry, in the country have stopped running - this is later referred to by Layburn as (paraphrased) 'the crisis in the North Korean economy'.
By the end of the movie, the fate of Ahn Chol was still undetermined, but it was later revealed that he eventually managed to escape, and that he still films in North Korea.
