Son of Evil [Film and TV Commentary]

On New Year's Eve, a mysterious killer massacred revelry crowds at a high-rise in downtown America from a distance. 29 people died, shot to death. No bullet casings, fingerprints or other evidence were found at the crime scene, and there was no trace of the killer. Three days later, the killer went on a killing spree in a large shopping mall. Dozens of citizens and security personnel were shot to death. A group of SWAT team members was also killed by the killer with grenades. FBI chief Landmark (Ben Mendelsohn) and his protégé, the young policewoman Elinor (Shailene Woodley), are ordered to investigate the case. However, the state government and the local police department all try to take credit and power, and even carry out special police operations that Landmark strongly opposes. However, the casualties caused by these actions are blamed on Landmark. It is extremely ridiculous and completely out of control. It is this absurd evil world that shaped today's killers. When the master and apprentice were desperate, Elinor discovered a key clue that brought her infinitely closer to the abyss of the evil world.
