A major of the South Korean army is taken prisoner during the Korean War (1950-1953). He attempts to escape but a guard shoots him. But a woman appears to save him. She is a student studying at Kim Il-Sung University. While his wound gets healed, he falls in love with her. She is also an anti-Communist. When he becomes healthy again, he sneaks into the Pyeongyang concentration camp to rescue three South Korean soldiers even though she strongly objects. He successfully carries out his mission and they set out for Seoul. But there are a lot of dangers waiting for them on their way.
