Season 1 opens with the LAPD’s new Priority Murder Squad (PMS), soon renamed the Priority Homicide Division (PHD), under the direction of Deputy Chief Brenda Leigh Johnson investigates the murder of a technological genius. Brenda has recently joined LAPD after a long career in law enforcement, including with the Atlanta and Washington, D.C., Police Departments. We soon learn Brenda is originally from Atlanta, Georgia, was CIA-trained, and was recruited by her former married lover, Assistant Chief Will Pope. Brenda is resented as an outsider by much of the LAPD and seen as an adversary by Robbery-Homicide’s Captain Taylor, who initially persuades her squad to request transfers en masse in an unsuccessful effort to force Brenda’s resignation. Brenda soon wins over her assistant, Sgt. David Gabriel, and the grudging admiration of the team when she shows them why she is called a closer; but her battle is far from over. As the season progresses, we see Brenda struggle to establish her authority and earn the respect of her squad, despite the efforts of Taylor and Detective Lt. Andy Flynn to both undermine her authority and hamper her investigations. Slowly, one-by-one, Brenda wins over her team; and, by season’s end, she has earned the loyalty of them all, even the hard-boiled Det. Flynn, as they stand united against Capt. Taylor’s final attempt to remove Brenda from the squad.
