During Shen Zhao's wedding live broadcast, a will suddenly popped up, pointing to a murder she had personally participated in but had concealed for many years. Qi Yansheng tried to shut down the live broadcast, but Lin Wanzhao raised questions in the barrage, and Zhou Sui'an's camera accurately focused on her trembling hands. And the silent Chen Yanqiu was writing the key date on the palm of his hand with a pen - that day, there was never more than one person who should have died. The truth is hidden behind every smiling face, and the viewers of the live broadcast are no longer bystanders.
