In order to please Mr. Park, who is in a wheelchair because of leg paralysis, Miko specially invited her former elementary school classmates to celebrate her birthday. Teacher Park likes Jin Minghao very much. Eun-young, Shi Hao, the vice squad leader who is about to get married, Taihō, the athlete, Shunzhi, the "Little Sister Pig" and Jacky, who are shy, all rushed over. At the celebration dinner, when everyone was chatting in a very good atmosphere, a chilling smell spread in the air. Shi Hao was the first to lose his temper. He accused the teacher of being crazy, because when Shi Hao was young, the teacher always disliked him and liked Hao Ming very much. In fact, every student here has similar bitterness and hates teachers. Taihō was slapped by Mr. Park because he fell in a relay race, and later he was sent to squat. As a result, his leg was injured and he became disabled. Eun-young was laughed at by the teacher because her family was too poor to afford a decent gift. Shunzhi was laughed at by his teacher because he was too fat as a child. Jacky was scolded by the teacher, and her mother died on her way to school. In fact, these students all want to kill Mr. Park with their own hands, but the crisis has quietly happened around them. Teacher Park once gave birth to a deformed son named Yongwen, but he never disappeared.

When these students appeared in the teacher's house, Yong Wen sneaked in. He killed Shi Hao, Eun-young and Taihō. Shunzhi accidentally fell off a cliff when he assassinated his teacher. As Yong Wen was about to kill Hao Ming, his mask was taken off by Hao Ming. It turned out that Jacky, not Yong Wen, killed his classmate. Finally, Hao Ming died, but Jacky ran away.

When the police learned the news, they began to look for Jeong Won. They saw a dead woman in Jacky's home, but the police found all the clothes in the closet were women's, and Jacky was a young man. So the police began to wonder what had happened. It turned out that it was none other than a witch who killed her classmates. Actually, the witch's name is Jeong Won. She is a student of Miss Park. She was laughed at by her teacher since she was a child, and what she said in her memory was actually her resentment against Jeong Won. She killed her classmates with poison because they laughed at her when she was young. Finally, Jeong Won had no desire to live, so he committed suicide by jumping into the sea, and Teacher Park committed suicide because of guilt.
