After many years as a patrol officer, Detective Jocelyn Rush is almost immune to the corruption that pervades the rougher streets of Philadelphia, but only almost. After saving her daughter from a kidnapping, she ends up in the emergency room and discovers that Anita, a former prostitute and acquaintance from her earlier days on the beat, has been brutally mutilated in a horrific attack. With the help of her partner and a special unit, the Special Victims Unit, Jocelyn finds out that Anita is by no means the first victim of such attacks. It also doesn’t look like she will be the last. As the violence comes ever closer, Jocelyn knows she must do everything to stop the sadistic attacker, even if it means confronting a terrible secret from her past.
