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)

When one of Debreno's first cases solved under Mannion goes to trial, the defense uses Debreno's troubled professional and personal past to discredit him, implying that he set up the defendant in order to impress Mannion. Now, as Mannion questions Debreno's motives, he must also decide whether or not Debreno has a future as a part of his team.
