In the heat of the moment, one of the others shot and killed an off-duty cop moonlighting as a security guard. Kat and her pals fled the scene in a panic, and no one was caught. Sixteen years later, Kat -- now Kate -- is a single mom with an eight-year-old son, who works as a prosecutor in the Philadelphia DA's office. But her dark past rears its head when she walks into court one day and discovers that she is to prosecute Mario Castellanos, one of her friends from that terrible night. Kate is in a bind: even though Mario was the one who probably did commit the crime, he's counting on Kate to make sure he's not convicted. When Mario is found dead -- in Kate's apartment, and with her pistol -- homicide detective Tom Braga shows up to investigate the murder. With her life and her son's in danger, Kate realizes that she has nowhere to turn. Except, maybe, to Tom...
