A starving toddler found wandering the streets alone leads detectives to the home of Manuela Ozuna and another child in grave condition. The police question Department of Child Services caseworker Keith Musio, whose vague and backdated reports on the family suggest he hadn't checked on the children in months. When the overworked Keith accuses his supervisor, Janette Grayson, of orchestrating the false reports, Chief Dodds promises to conduct an internal investigation. But when neglect leads to death, Barba takes matters into his own hands and arrests them for manslaughter. Meanwhile, Dodds indicates some changes coming to Benson's squad.
