The night in Linyuan City is never peaceful.
When "rules" become a butcher's knife hanging over the head, every cold text contains a hidden murderous intention - the warning of "no walking in the corridor after ten o'clock" on campus, the curse of "message must be answered in three minutes" in the office building, the taboo of "no mention of children" in the nursing home, are all the threads of the invisible giant web. Violators are either swallowed by the shadow, trapped in an endless cycle, or forget themselves and become the nourishment of the rules.
In order to track down his sister who disappeared mysteriously three years ago, former criminal policeman Yang Hao stepped into this city controlled by the "Web Weaver". He disguised himself as a school worker and sneaked into a closed dormitory building, became an intern and got stuck in a deadlock of overtime work, and touched the forgotten secrets of the nursing home as a volunteer... Every time he solved the puzzle of the rules, he was shocked to realize that there were more piercing social scars hidden behind it, and the truth about the web weaver was actually tightly entangled with the pain and despair accumulated in Linyuan City for hundreds of years.
Are rule loopholes a way out or a trap? Is the mysterious "Rule Keeper" a friend or foe? When victims from different corners gather together due to a common fear, can they use courage and empathy to tear through this web of death woven by human negative emotions?
"Remember, rules are not protection, they are cages."
