This film mainly tells the story of the South American spy trio headed by Yuan in South Korea and a series of stories that happened after being abandoned by North Korea. It can be said that it is gratifying, sad and sad.
Two years ago, North Korea's 5446 secret special forces sent Yuan (Kim Soo Hyun), a five-star captain, to sneak into Moon Village, a very ordinary Korean village, as a spy. Yuan alias Fang Dongjiu, pretending to be a fool, settled in a stingy aunt's house. He mingled with the local people and secretly understood the political and military tendencies and ideas of the Korean people.
His heart has been waiting to complete the task and return to the motherland to reunite with his mother, which is also his spiritual pillar and belief.
One day, Li Hailang (), the leader of the Black Dragon Club who is an enemy of Yuan, and Li Xuanyu, a junior who regards Yuan as his mentor, appeared in the village one after another. He felt some changes. ...
One day, an order against the spy of 5446 troops came, and the fate of three young people ushered in the most severe barrier. Because of the change of national politics, they are no longer needed as "infiltrators-dark people", so they are ordered to commit suicide collectively, and other latent players are forced to obey orders. In the end, only the three of them were left, labeled as "treason" and strangled.
Senior officials in South Korea intend to protect them, but as soldiers, they can't betray their country even if they die. Faith has already penetrated into the bone marrow, and the last three people chose to die after resisting. )
