Nash butts heads with a cop whom Nash thinks is dirty. When he kills him and two other cops, he arrested because there's some personal stuff between them which is believed to be the actual motive for their feud. Bettina is assigned to defend Nash and he brings in a cop from Internal Afffairs, Caitlin Cross to find out the truth. But she's operating under the assumption that Nash is guilty. Nash also claims that he thinks that there was another man at the shoot out, who got away, whom he thinks is their partner.
