The BAU team is on the trail of a stalker who followed a woman across state lines and will stop at nothing to gain her affection.

Morgan, Prentiss, Reid and J.J. attempt to stop a stalker before he gets close to the woman who is the object of his affection.

Meanwhile, Hotch and Rossi consult on a murder case to determine if a wife who killed her husband can claim battered-woman syndrome.
