A brutal war in the 1970s left Cyprus split in two and displaced a third of its population. Ben spends a week with the UN's Peacekeeping Force, who patrol the enormous buffer zone on the island, keeping the Turkish and Greek Cypriot communities separated. Ben is on a mission to understand more about the so-called 'Cyprus Problem', visiting ghost towns left behind, learning how criminal gangs profit from the division and hearing often tragic stories from people on both sides whose lives have been devastated by the conflict.
