In 1991, South Korea is preoccupied with it's first democratic elections in thirty years. But in a village in Daegu, five fathers are facing their worst nightmare. Five young boys went on a romp in the mountains and never returned. At first, the media is too caught up with the elections to cover this as news, and the local police treats it as a runaway case-until it attracts attention on a TV show. Soon the "frog boys" become national news. But with no credible leads, the mystery remains. A decade later, the boys' bodies are found near a military shooting range. But to this day, the case has never been fully investigated. At it's heart, this is the story of five heartbroken parents and their missing children, but it is also a wider story about the societal changes that have taken place in Korea over three decades.
