In the season 16 premiere, Sergeant Benson juggles work and her new role as foster mother to baby Noah Porter. Amaro, now working the traffic beat in Queens, arrests an underage prostitute with connections to Noah's mother Ellie, who was "greenlit" by her pimp and brutally murdered. Amaro's undercover work sets off a chain of events that puts everyone connected to the case - even baby Noah - in danger. Meanwhile, a new detective assigned to Manhattan SVU starts off on the wrong foot.
