The Tree [孩子。树]

A man is found dead on the road. The police are on site to collect and examine the evidence. According to the police officer, it appears to be a straightforward hit-and-run accident until a pathologist operates on the deceased and suspects otherwise. The only witness to the accident is a 9 year-old boy who was found hiding behind the branches of a tree and he happens to be the deceased stepson. Hence, the investigation begins.
