Narc is a 2002 American neo-noir crime thriller film directed and written by Joe Carnahan and starring Jason Patric and Ray Liotta (who also co-produced). The plot revolves around the efforts of two police detectives in search of the murderer of an undercover police officer. As they investigate, they engage in unethical behavior and uncover dark secrets that will challenge their fragile relationship. Plot Undercover narcotics officer Nick Tellis chases a drug dealer through the streets of Detroit. Tellis shoots and kills the dealer when he holds a child hostage, but a stray bullet hits the child's pregnant mother, causing her to miscarry. Eighteen months later, Tellis is tasked with investigating the murder of an undercover officer, Michael Calvess. Tellis reluctantly agrees to take the case on two conditions: that he will get a desk job if he secures a conviction, and that he is partnered with Detective Henry Oak, whom Tellis has read about in the Calvess case file. The police chief accepts Tellis' conditions, but warns him about Oak's instability. During their first meeting, Oak reveals to Tellis his belief that the department wants the Calvess case buried and it is all about politics. The detectives visit the scene where a drug dealer has been shot dead in his bathtub; Tellis surmises the death was accidental and self-inflicted. Tellis notes that the shotgun at the scene is a SWAT weapon with the serial number filed off. While the partners have a discussion about family, Oak recalls a drug bust decades prior, where he found a ten-year-old girl who was being sold into prostitution by her stepfather, resulting in Oak beating the man; he sees parallels with the current case. Tellis visits Calvess' widow Kathryn, and asks about her relationship with her husband while he was on the street. Oak, who is protective of Calvess' family, turns up at the house and angrily confronts Tellis. The detectives next visit the home of a man involved in Tellis' shooting. Although they find no evidence to suggest he murdered Calvess, they find another officer's badge on the premises. The man pulls a gun and wounds Tellis before Oak kills him in self-defense. The case assailant is determined to be Calvess' killer and the case is closed. However, Tellis and Oak are furious as they believe the killer has yet to be found and continue to investigate independently. When the detectives visit
