The beaten body of a five year-old girl in foster care is found. Detectives Benson and Stabler investigate her complicated family ties. They learn the girl's birth mother always tried to get back her daughter from the foster mother (played by Kathleen Wilhoite) and grandmother (played by Piper Laurie), who was responsible for the girl before she died. They then investigate her foster brother. Captain Cragen manages to reach him with the help of a video game.
