Wrapping up a normal day at the office, criminal psychologist Kieran Finnegan is accosted by a desperate woman who shoves an infant into her arms and then flees, only to be murdered minutes later on a busy Manhattan street. Who was the woman? Where did the baby come from? Kieran can't stop thinking about the child and the victim, so her boyfriend, Craig Frasier, does what any good special agent boyfriend would do--he gets the FBI involved. And asks Kieran to keep out of it.
