1, the ending is that Yuan was shot several times and jumped to his death on the roof with the opposition sent by North Korea. The film tells the story of a North Korean spy, Yuan, who accepted a secret mission codenamed "Flower of Red Cliff" and sneaked into Moon Village, a small village in Seoul, South Korea, to mingle with the villagers, secretly collect Korean thoughts and attitudes towards politics and report to the North Korean government. The reason why he became a spy is not only to show his loyalty to his motherland, but also to protect his mother's safety.

The first half mainly talks about some trivial things in a small village. Dong Jiu, a fool, is bullied by children every day. Although he will scold them a thousand times in his heart, he will still stand up when the children can't find them. I giggle at the goddess every day, but when the goddess is bullied, she will secretly retaliate against her. I often secretly enjoy eating a piece of meat from my employer's house, whispering to my honest courier uncle, and playing with Huang Mao guitarist Li Hailang as an enemy. These look very harmonious.

In two years, the villagers' behavior gradually warmed this "monster" who had received special training since childhood. However, as soon as the picture changed, organizing suicide missions made soldiers' instinct to perform tasks fail for the first time. He went to the barber shop and cut off his messy hair. On the way, he told Ilulan, who secretly loved him, that his younger brother could rely on him, told him to study hard, cheered on his uncle who wanted to pursue love, and gave the money he had accumulated for two years to Ilulan to find the lost child. In the house, I had the last meal with my aunt who took care of me for two years. My aunt took out the clothes he had just worn, and there was a passbook in it. How many times I thought my aunt knew Dong Jiu's identity, but her performance puzzled me. Dongjiu said goodbye to everyone, so he said goodbye.

Holding the loyalty to the motherland, he was prepared to die for the motherland, but he heard that his mother was executed by the motherland. Faced with the betrayal of his motherland, he was desperate. Although South Korea extended a helping hand to them, they did not compromise. Their greatness is a spirit. Even if abandoned and resented by the motherland, it will not live. This also shows the spirit of their soldiers. The story ends with an aunt's monologue. Everyone in the village is thinking about Dongjiu. Aunt came to the place where Dong Jiu was filmed, and their photos were hung on the wall. The back of the photo says, "Mom, don't get sick." It leaves us a lot of room to imagine whether they are still alive.
