Reply 1972! From an elementary school teacher to an Japanese military officer. Becoming an South Korean officer after liberation, again from a party member of the workers' party to an anti-communist leader. The soldier, the rebel leader, then the president and again the second and third president. He, who wanted to realize the visions of his lifetime. But anyone who caused disturbance, has been tortured, then killed and vanished. A man, who caused so many deaths in this country and made a whole generation go mad. This film is about those days. It is the story of people who lost their lives. It is a story of a time, when we struggled against it. The spirit of fourty years anniversary of Yusin - a passionate goodbye!
