A 911 call from 9-year-old Maria is forwarded to Benson, who must figure out why Maria has been locked in a room for days. A trace on the cell phone Maria is using turns up multiple phony leads, corrupted due to electronic manipulation of the phone's signal. Benson eventually convinces Maria to divulge crucial clues, including the name of her captor, Ronald, and a receipt from Felipe's burger joint. As Fin discovers that Felipe's burned down months ago, Novak locates Maria's mother through the Honduran consulate.
