The specific plot of Apartment is: Shizhen is a single woman, living in a luxury apartment and living alone every day. One night, on her way home by subway, she met a woman in red with heavy makeup, and she wanted to pull her off the track. Seeing that the subway was coming, she cruelly broke the hand of the woman in red. After this incident, she was mentally tortured every day and even had nightmares every night.
Shizhen met Yan Rou, a disabled girl in a wheelchair, in the opposite apartment. Jou-yeon is a poor girl. She is disabled and her parents are dead. But fortunately, everyone in the apartment is very kind to her. The girl seems to like her very much and gave her a Rubik's cube. I don't know when it started, Shizhen found that the apartment across the street would turn off the lights at 2 1: 56 every night, as everyone agreed. There have been several murders in the apartment across the street. Driven by curiosity, Shizhen began to observe the apartment opposite with a telescope.
After several days of observation, Shizhen believes that the murder case in the apartment opposite is related to the collective turning off of lights. She told the police officer Yang, who was in charge of the case, what she found. It's a pity that officer Yang obviously doesn't believe her. Shi Zhen, who didn't want to see her death again, went to the apartment opposite and told them not to turn off the lights at 2 1: 56 pm. But nobody paid attention to her. They still turn off the lights at 2 1:56 every night as before.
Finally, officer Yang caught a suspect, a single man living in Fortune Apartment 704. He told police officer Yang that he was controlled by the ghost, and everything he did was an order for revenge. Officer Yang treated him as a psychopath. The suspect who was afraid of Zhou Yan's revenge shot himself.
Shizhen found the law of female ghost killing from the Rubik's Cube. She hurried to the apartment opposite. She found a key to 704 from the victim. Then, she found 704 and opened the door. Shizhen sat in the chair where Zhou Yan sat before she died. Everything that happened to Zhou Yan began to appear in her mind. It turns out that Zhou Yan committed suicide as early as last Christmas. After her parents died, the people in Fortune Apartment kindly took turns to take care of her. Later, everything changed. The friendly faces of the neighbors became evil. The loving mother-in-law began to force her to eat a lot of food; Good doctors and couples began to regard her as a drug experimental machine; Friendly guys started raping her. ...
Shi Zhen woke up. She saw Yan Rou, who had become a ghost. Jou-yeon told Shizhen that she couldn't stand everyone's neglect instead of abuse. She also told Shizhen that the woman in red at the subway station was her. She had hoped that Shizhen could make amends, but Shizhen finally let go.
The frightened Shizhen opened the door and fled to the rooftop, but Zhou Yan followed, and she could not escape. Shizhen, who knew she was going to die, told Zhou Yan to save her, and she regretted it. Finally, Zhu Yan pushed Shizhen downstairs. Shizhen died, and her resentment made her the next spectre.
