A body is washed ashore on a crowded beach. The detectives are quick to identify the dead man, an heir to a waste disposal fortune, as someone reported missing after reportedly falling off a yacht. The small number of people on board the yacht at the time of the accident means a limited number of suspects but leads the detectives into the investigation of the power struggles inside a divided family and the effects of violence. The investigation reminds Joe of his own troubled childhood and has him questioning his own parenting skills. Sophie and Theo compete for a spot in an undercover training course. Nicole, back at work part time, receives some good news.
