The year is 1997. North Korea is suffering from a devastating famine that has shaken the foundation of the ruling class. A series of high-profile defections to the West has led the reclusive country’s leadership into the grasp of paranoia.

Nuclear scientist Han Chol-Soo is on a tenuous diplomatic mission to the United States. There he is forced to embark upon a high-stakes pursuit after his wife disappears with their newborn son. Paralyzed with fear at the repercussions of her decision, Han turns to his colleague Park Jun-Young for help—a man that he suspects is an intelligence operative.

He soon regrets his decision as Park cuts a swath of mayhem in the name of helping Han, and the chase forces Han to confront the harsh realities of his home country.
