Detective Waters, a black man, speaks of how people in Los Angeles almost assist upon getting into car accidents. Waters, who had been in the car involved in the accident, gets out of the car to inspect a crime scene in the immediate vicinity. Waters is told by a fellow police officer that a body had been discovered; however, what Waters sees at the crime scene is not immediately known to the audience, for the scene jumps to a lengthy montage of scenes that took place almost two days prior to the accident: Inside a gun shop, a Persian father, Farhad, and his daughter, Dorri, are purchasing a gun, but are hampered and hurried from the shop by the shop owner, who is against the two not speaking English; the defense attorney and his wife, Rick and Jean, are carjacked by two black men, Anthony and Peter; Jean is having the locks changed on her house, and the locksmith, Daniel, overhears himself being regarded as a gang member; in a diner where two Asians are conversing amongst themselves, a police officer, Ryan, is on the phone with a medical assistant, Shaniqua, who promptly hangs up when he makes a racist comment.
After Ryan and his partner, Hansen, leave and begin their duties, they pull over a black vehicle on suspicions of sexual activity while driving. The black couple, Cameron and Christine, exit the vehicle when Ryan directs them to; Cameron is polite and cooperative, though Christine is drunk, which shows through her actions and speech. Ryan frisks Christine, though what he is essentially doing is sexually molesting her. After he finishes, he allows the couple to continue on their way.
Another series of montages begins again, going off of the original scenes, continuing from the previous montages. Christine is beside herself with anger that Cameron did nothing to stop with Ryan had done to her, though Cameron firmly believes that he acted in the way that he was supposed to; Daniel is putting his daughter to bed
