Zhou Xiaoman, a deaf-mute female worker, died on an iron bed with sheets wrapped around her neck and suffocated. The last text message on her phone read: Sister, I found the evidence and will go to the police tomorrow.
The only witness, Ah Qiao, could not speak and could only use sign language to describe a man wearing glasses. Security captain Wang Debiao immediately surrendered, but his confession was full of flaws.
Interpol Shen Yan chases down HR Director Chen Wei - behind this gentle manager wearing glasses, there is a chain of intermediaries for deaf-mute female workers: withholding IDs, withholding wages, forcing them to work overtime, and sexual assaults are covered up by their inability to speak.
Shen Yan dug out his father's old work badge from fifteen years ago in the archives. That year, his father died unexpectedly at the Hongda Factory, and the handwriting on the certificate was highly consistent with Chen Wei's.
Ah Qiao disappeared and was intercepted, and the video secretly recorded by Zhou Xiaoman was handed over - irrefutable evidence pointing to Chen Wei. Shen Yan reported to the higher level and confronted the old workshop. Wang Debiao recanted his confession and told the truth about the murder of Shen Guoqiang fifteen years ago under the instruction of Chen Wei.
In court, Ah Qiao told everything with both hands. The silent ones finally bear witness for themselves.
