In the closed world of North Korea, Yuna’s sister Minjee is desperately sick. To save her, Yuna pays a Smuggler to help them flee North Korea – but Minjee is too sick to make it across the border. Instructed by the Smuggler, Yuna races across time and space to New York, committed to returning for Minjee. Yet the free world is seductive and confounding: life suddenly offers Yuna a distracting bounty of choice, and time moves much faster than in North Korea.
