Still shaken from his recent brush with federal investigators, Kellerman (Reed Diamond) takes time off to seek counseling. As for the others in the homicide unit, Lewis (Clark Johnson) and Pembleton (Andre Braugher) investigate the murder of a wealthy woman, only to have their chief suspect accuse the cops of stealing the victim's diamonds in the autopsy room. This development prompts medical examiner Cox (Michelle Forbes) to reluctantly ask Brodie (Max Perlich) to spy on her staff. And on the domestic front, Pembleton's wife, Mary (Ami Brabson), is drawn into the growing animosity between her husband and his former partner Bayliss (Kyle Secor). ~ Hal Erickson, Rovi
