Invisible Evidence

After a car accident, a blind girl named Thu reports to the police about the incident that she believes to be fatal. However, because she is blind, she encounters difficulties in persuading the police to believe her. At the same time, Hai, another witness of the incident, suddenly appears with conflicting testimonies about the crime scene. While the police is having a headache verifying whose information was true, the killer secretly follows both Thu and Hai to kill the witnesses.
