A seemingly routine murder investigation by the LAPD Robbery-Homicide Division is interrupted by the arrival of Deputy Chief Brenda Johnson, the new head of the LAPD’s Priority Murder Squad. An outsider from Atlanta in her first week of service, Brenda has already begun to face the resistance of long-time high-ranking officers, particularly Capt. Taylor of Robbery Homicide, as well as the questionable confidence of her own squad, who have decided to request transfers en masse. Only her assistant, Sgt. Gabriel, seems willing to try to work with her.
