Four women who were said to be "too sensitive" were pushed into the same chain of responsibility because a project failed. They don't seek revenge, they just check the facts.
Lin Wan had been giving in in her marriage for many years, until an old debt caused her husband's silence. Xu Zhiyi was pushed to the front of the project accident, only to discover that the materials had been altered long ago. After Chen Qingqing returned to work, his identity changed from a participant to a "visitor." Zhou Man just wanted to clear up the divorce, but when checking the accounts, he discovered a longer chain of responsibility.
After handing over four pieces of materials, they realized that the people who were really afraid of them speaking out were not afraid of trouble, but because someone finally started to check the facts.
