Two North Korean agents, carrying Japanese passports bearing the names “Shinichi” and “Mayumi”, plan to explode a Seoul-bound plane in mid-air. They are diverted to another plane after they have planted the bomb. When the plane crashes, killing all on board, the two plan to commit suicide. The man succeeds, but the woman is saved through medical intervention. When she witnesses the suffering of the surviving families of the bombing victims, she begs to be executed, believing it is the only fitting punishment for her actions. ~ The film is based on the life of Kim Hyun Hee, a North Korean agent.
