Their recovery window is small - and every case is a race against time. Agent Jack Malone and the members of the FBI's Missing Persons Unit use advanced profiling techniques to peel back the layers of a person's life. No lies, deceptions, or evasions can withstand their withering scrutiny. Because they know that only by revealing every fact of a missing person's life, can they track where that victim may be. You find out who they are, and you'll find out where they are. But you don't have time to get it wrong. Because after 48 hours, most victims are gone forever.
