Seoul: North Korea is considered one of the most secretive countries in the world. It is officially an atheist state. The ruling party sees religion as a threat to its authority. Instead, North Koreans are expected to show complete devotion to the ruling Kim family, who many view as godlike. There are believed to be a small number of Christians practising in secret inside the hermit kingdom, but entire families can be sent to prison camps for practising religion. Even owning a Bible can lead to detention or even death.

According to BBC, there are an estimated 33,000 North Korean defectors living in South Korea. The exact number of North Korean Christians living in the south is unknown, but it is believed that a significant number of defectors now identify as Christians. BBC correspondent Danny Vincent travels to the South Korean capital of Seoul to meet a family of defectors he first met a decade earlier while fleeing Northern China. The story of these defectors sheds light on the perilous journey faced by those who escape the oppressive regime in search of religious freedom and a new life in South Korea.
