A woman who was driving home late at night is found beaten and raped after being stopped by a police officer for a traffic violation. After talking to the woman, Mannion discovers that this is the latest in a series of attacks allegedly perpetrated by a police officer. Now, after Mannion conducts an internal investigation of his officers and fingers start pointing at Cutter, Debreno is thrown for a loop when his estranged wife (Farentino) informs him that she was attacked in the same exact way.

Meanwhile, Preston Kembridge, a mayoral candidate, tempts Nick with an offer to run his campaign. (from CBS)

Mannion goes head-to-head with the U.S. Attorney General and a tough civil-rights lawyer (Jaclyn Smith) in an emotionally charged episode. The investigation into the murder of an 11-year-old girl turns up the child's photo on a porn site, prompting Mannion to seek help from Attorney General Hatcher to toughen legislation against Internet child pornography. But Hatcher has an agenda of his own. In other cases, the chief is asked by a congressman to look into a case involving the alleged accidental death of his son, and a high-profile lawyer (Smith) accuses an officer of using excessive force.
