With police struggling to stop this brutal business, Jean Mackenzie heads on a journey into Romania's underworld to expose how it all begins.

"The tiny village of Taesung sits deep in the heart of Korea’s Demilitarised Zone – the strip of no-man’s land separating North and South Korea. "The community of South Koreans, many aged in their 80s and 90s, live mere metres from North Korea, meaning they must be guarded day and night by hundreds of soldiers. "The village was established at the end of the Korean War as a symbol of peace, but 70 years later, the Korean Peninsula is still divided, and over the past year tensions between the two countries have flared. "The BBC’s Seoul correspondent Jean Mackenzie has secured rare access to the village, the people who live there and the soldiers who guard them. Filmed and edited by Hosu Lee."
