When the film broke out that a young man coming from a rich adopted family murdered his birth father, the controversy around the case hit a nerve with the public at large. An experiment was held through the form of virtual court inside a college to discuss this hot topic. During the process of virtual court, 12 Chinese people from different walks of life got together and discussed the case like a jury.
