Charles Coleman, a successful African-American judge, has his world turned upside down when his son, CJ, is killed by two police officers during a traffic stop. His grief-stricken pursuit of justice hits a wall when the system that he's a part of protects the officers from charges by wiping all the evidence that could have condemned them. Coleman's torment is compounded by the fact that the officers misinterpret CJ's attempt to pull out a phone for a weapon. In the aftermath of his son's death, Coleman begins to question the principles he's built his career upon.

Vowing that his son's death will not be in vain, Coleman teams up with Javier, a mechanic whose son was also killed under similar circumstances and who has found evidence that could prove the officers' guilt. Together, they decide to take the law into their own hands. As they delve deeper into their quest for vengeance, Coleman's colleague and friend, Horace, a detective played by John Cusack, grows concerned about the path Coleman is taking. The situation escalates as the two grieving fathers commit to a course of action that will change their lives forever, confronting the failings of the legal system and their own inner turmoil in confronting personal loss and the desire for justice.
