Who is Kyra Sedgwick

At work, L.A. Deputy Chief Brenda Johnson is a woman in charge. Got a suspect to grill, a case to crack, a murderer about to walk? Call Brenda in and watch the fireworks. But at home...well, that's another story. Kyra Sedgwick headlines a sizzling 4-disc, 15-episode Season 5 of the series that combines heart, humor and homicide into a show that's equally compelling as a police procedural and a personal drama. As a cop, Brenda takes on everything from a corpse that comes COD to a serial killer to Sharon Raydor, an internal affairs officer as tough as she is. As a civilian, Brenda loses one family member and gains another: her surly niece Charlie. Brenda can outsmart, outmaneuver and out a killer. But can she handle a teenager?
