Harry Bosch finally learned the truth behind his mother's murder, and the horrible truth made him furious. How can he seek justice in a broken judicial system? How can he maintain his integrity and honesty? This season, Bosch will investigate the murder of a homeless veteran, the suicide of a serial murder suspect, and the high-profile murder trial of a Hollywood director. In the process, Bosch will face a variety of cold-blooded opponents who have only one common goal - to completely destroy him. Jeffrey Pierce will play the fragile Trevor Dobbs. Although he has left the army, the army has not left him. He served as a lieutenant officer in a well-organized special forces unit and went to Anwar Province, Iraq to perform missions. Christopher Backus plays Woody Woodrell, a former special forces soldier who now works for a private security company. Linda Park plays Jun Park, an elementary school teacher, who is also a member of the "Mayor's Crisis Response Team". The team is a unique organization in Los Angeles. A group of volunteers will assist the Los Angeles Police Department in dealing with emergencies at suicide and murder scenes after receiving special training. Their main job includes comforting the families of the deceased, communicating with these families on behalf of the police, and coordinating between the families, the police, the forensic doctor and other relevant agencies. Arnold Vosloo plays the former police officer Rafael "Rudy" Tafero, who is now the security director of Andre Holland. He and Bosch are like water and fire, and even fabricate false evidence in a case to frame Bosch.
