Plot
Los Angeles Detective Graham Waters and his partner, Ria, are involved in a minor car collision with Kim Lee. Ria and Kim Lee exchange racially charged insults. Later, Waters arrives at a crime scene, where he discovers an unidentified corpse.
48 hours earlier, Anthony and Peter, two young Black men, carjack district attorney Rick Cabot and his wife Jean. While driving, Peter places a figurine of St. Christopher on the dashboard. They pass by Waters and Ria, who are investigating a homicide in a San Fernando Valley parking lot. The pair learn that a White undercover cop, Detective Conklin, shot a Black undercover cop, Detective Lewis, unaware that the other was a policeman. At home, Cabot says the carjacking incident could cost him re-election, believing that he will lose either the Black vote or the law and order vote. Hispanic locksmith Daniel Ruiz overhears Jean, who suspects that Daniel is a gangster, demanding that the locks be changed again.
While searching for the Cabots' stolen vehicle, Sergeant John Ryan pulls over an SUV driven by a wealthy Black couple, TV director Cameron Thayer and his wife, Christine. Ryan performs a body search on Christine and molests her in front of Cameron. Ryan's younger partner, Officer Tom Hansen, looks on in horror but does not intervene. Hansen reports Ryan's conduct to Lieutenant Dixon and requests a transfer. Dixon, a Black man, tells Hansen that a racism complaint would hurt his own career and allows the transfer in exchange for silence on Ryan's conduct. Ryan, who lives with his ill father, takes his frustration out on the Black HMO administrator he speaks with over the phone.
Anthony and Peter accidentally hit an Asian man while driving and drop him off at a hospital. Meanwhile, Waters visits his mother, who asks him to find his missing younger brother. Ryan again encounters Christine, who had gotten into another car crash. Recognizing Ryan, Christine frantically resists his assistance. He manages to pull her out of the car just before it is engulfed in flames. As Christine is being helped by paramedics, she stares at Ryan. Waters is summoned to a meeting with DA worker Flanagan, who tells Waters that Internal Affairs wants Conklin imprisoned. Waters has evidence incriminating Lewis, but Flanagan promises Waters a promotion and the expungement of his brother's criminal record. At a press conference, Waters reluctantly confirms that the homicide was racially motivated.
Anthony and Peter unsuccessfully carjack Cameron's car, and Peter flees the scene before the police arrive. Cameron and Anthony drive away and are chased by police, including Hansen. When police catch the SUV, Hansen recognizes Cameron, and out of remorse for the earlier traffic stop, he vouches for Cameron to be let off with a warning. Anthony, who was hiding during the exchange, is dropped off at a bus stop by Cameron. Later that night, Hansen picks up a hitchhiking Peter. Peter reaches into his pocket, and Hansen, thinking he is reaching for a gun, shoots him. Peter, who was actually reaching for his statuette, dies. Hansen hides the body and burns his car. Waters and Ria later arrive at the scene, revealing that the dead body is Waters's brother Peter. Waters's mother disowns him over Peter's death.
Anthony comes across a white van and takes it to a chop shop, where they discover chained Cambodian immigrants. It is discovered that the van had belonged to Kim Lee and her husband, the man that Anthony and Peter had hit. The chop shop owner offers Anthony $500 per immigrant, but Anthony refuses. Anthony drives the immigrants to Chinatown and frees them. He passes by a fender-bender. One driver is the insurance adjuster Ryan had previously argued with, and the other is an Asian man. An exchange of racially charged insults erupts between the drivers.
