Plot summary
Goren and Eames investigate the murder of Lois Romney ( Funda Duval ), a pregnant woman who has given up her drug addiction and is struggling to stay clean. It initially appears that the murderer is the victim's unstable junkie boyfriend, Dale van Acker ( Geoffrey Nauffts ). However their investigation leads them to the boyfriend's wealthy and domineering socialite mother, Priscilla van Acker ( Kathleen Chalfant ), a sociopath who disapproved of her son's girlfriend and arranged to kill her and frame her philandering husband at the same time.
