In June 1980, Rim Byeng-ho, a North Korean intelligence officer posted to East Berlin, Germany, attempts to cross Checkpoint Charlie with the intention of defecting to South Korea. During his attempt to cross to West Berlin, he is shot and wounded by North Koreans attempting to prevent his defection. South Korean agents successfully retrieve Rim from no-man's land, and congratulate him on his freedom. A week later, Rim is under brutal interrogation by South Korean Intelligence, who suspect he is a spy despite Rim's steadfast denials.
