Silent Witness is a 2013 Chinese crime thriller film written and directed by Fei Xing and starring Sun Honglei, Aaron Kwok and Yu Nan.

This allegedly happened after Lin Mengmeng had fled the scene after knocking Yang Dan's down with her red Cayenne SUV.

In the next court session when Lin Tai was examined, Tong Tao and his staff got an anonymous email that claimed that the sender had video evidence of the murder of Yang Dan.

As she was comparing this video, which was shot at an angle different from the security camera feed that was overlooking the scene, she noticed that the movement of Sun Wei's leg was inconsistent.

She immediately asked her staff to investigate whether Lin Tai had carried out a massive renovation job within the last few months and also whether he had purchased a lot of second-hand vehicles.

The story ends here, leaving the audience a strong sense that Lin Tai had been acquitted, as well as experiencing the power of fatherly love.

[2] Andrew Chan of the Film Critics Circle of Australia writes, ""Silent Witness" is an accomplished and matured court drama thriller, muddled within the essence of parental love, deeper emotions and twists and turns.

Director Fei Xing has successfully created a film that touches the audience's heart and expresses universal themes and messages at its core.
