On a rainy night, the community was sealed off and the murderer was on the loose. As soon as tenant Zheng Chuan locked the doors and windows, there was a knock on the door from the "police". The group was all cooperative, but he was the only one who noticed something strange. The six "searched" residents happened to be all the active accounts in the group. When he found that his mobile phone signal was blocked and time was strangely stagnant, he realized that he was trapped in a live broadcast game. The real murderer is not a person, and the real prey is not him. When time stops flowing, the only person you can trust is yourself.
