In the early 2000s, Adrian Hong was a soft-spoken Yale undergraduate looking for his place in the world. After reading a harrowing account of life inside North Korea, he realized he had found a cause so pressing that he was ready to devote his life to it. What began as a trip down the safe and well-worn path of organizing soon morphed into something more dangerous. Hong journeyed to China, outwitting Chinese security services as he helped asylum-seeking North Koreans escape across the border. Meanwhile, Hong's secret organization, Cheollima Civil Defense (later renamed Free Joseon), began tracking the North Korean government's activities, and its volatile third-generation ruler, Kim Jong-un. Free Joseon targeted North Korean diplomats who might be persuaded to defect, while drawing up plans for a government-in-exile. After the shocking broad-daylight assassination in 2017 of Kim Jong-nam, the dictator's older brother, Hong, along with U.S. Marine veteran Christopher Ahn, helped ferry Kim Jong-nam's family to safety. Then Hong took the group a step further. He initiated a series of high-stakes direct actions, culminating in an armed raid at the North Korean embassy in Madrid--an act that would put Ahn behind bars and turn Hong into one of the world's most unlikely fugitives.
