After Jim Dunbar loses his eyesight during a gunfight, the rehabilitated homicide Detective attempts to return to active duty at a new precinct. Facing opposition and doubt from his coworkers and Lieutenant, he is relegated to handling a car theft case with Detective Karen Bettencourt. Dunbar soon discovers that the recovered missing car might be connected to a larger ongoing serial homicide investigation.

The mounting frustration and pressure for Jim to prove himself and make things work as a detective and a person creates more tension with his colleagues and Karen as they collectively investigate the murder of a young boy. Jim's insecurities also begin to seep into his personal life at a dinner party with Christie's coworkers when out of jealousy; he threatens his wife's boss whom he believes was trying to flirt with her. His behavior puts additional strain on the marriage as it brings up unresolved issues for Christie about his past infidelity.

The 8th precinct is distraught when one of their detectives from the anti-crime unit is found murdered. Carl Desmond was shot in the head and his body was thrown in a dumpster. His colleagues and grieving widow, Mary Beth suspects that his murder was an act of revenge by someone he had previously put away. Karen is put in charge of the case, as she and the rest of the detectives must tread carefully in the investigation into the murder of one of their own. When Mary Beth's past infidelities come to light, Tom and Marty investigate a married man named Don Bellamy whom she was having an affair with. While going in a different direction, Karen and Jim put their reputation on line with other cops at their squad when their main suspect is Carl's partner, Eric who had put in a request for a transfer a week before the murder.

Jim struggles to move on with his life, but a joint investigation with the 77th precinct pairs him and his current colleagues with Terry Jansen and another detective as they investigate the murder of two gang members. When they head to the home of Titus Oliver, a possible suspect with a previous criminal record for an interview, he attempts to escape by running up to the roof of his apartment. Terry goes after the suspect alone, and ends up being shot in the shoulder. He tells the other detectives that Titus had fired at him and then he shot back with his 9mm gun.

The detectives interview a white supremacist in prison named Leonard Mattis who might be connected somehow with the attacks due to him being related to the victims through blood and marriage. He denies any involvement. They don't believe him as Mattis' wide range of power and connections in and out of prison is a major factor in these assaults. Meanwhile, Jim's patience begins to wear thin as his growing agitation over Marty's actions against him becomes more apparent to the other detectives at the precinct. Also, the fear of no longer being someone who is adequate enough to be there for and protect his wife and partner begins to take hold, as the investigation potentially endangers Karen and causes Jim to sporadically visualize Christie as a victim.
