After investigating the children's stepmother (his second wife), they turn to a pair of nannies (Tammy Blanchard and Merritt Wever), one of whom works for the family. However, the detectives must reach back to the nannies' history as children, and a television soap opera, to better understand the motives for the crime.

A businesswoman (Linda Lavin) becomes a suspect in the murder of her daughter-in-law, who was strangled in her garage. Disparate bruises on her body lead Goren and Eames to believe that there were two assailants.
