Before Detective Knight thought only about work, but after getting out of prison and hunting for bloody Santa Clauses, the hero remembers those he really cares about. While James unsuccessfully tries to establish contact with his ex-wife and daughter, his colleagues from the LAPD insult and beat up paramedic Desi, who dared to look into their bar. For the unstable ER doctor, this becomes the last straw. When he gets his police badge and uniform in his hands, the guy, feeling empowered, turns into a brutal killer. Desi has a special plan for her hometown on Independence Day, and only Detective Knight can stop him.
