In Atlantic City, New Jersey, two women have thus far been identified as having died at the hands of the same killer. Both victims were drug-induced paralyzed and still conscious during their two-month abduction, but otherwise well taken care of. Both were also petite but physically fit, and in life were fashion conscious, although the clothes in which they were found did not match what they would have worn in real life, these new clothes which were more doll-like. And both dead bodies were found in a place that represents a fun childhood, one on a playground swing, another on an amusement park carousel. Because the two women have no other similar characteristics beyond their small stature, the BAU believe the unsub to be a woman who is "collecting" the victims as surrogates for a doll collection that the unsub has lost. When the BAU learn more about the doll line that the unsub is mimicking and after one of the pieces of clothing is analyzed, they stumble across a lead to the unsub and the reasons for her actions. But time is running out for the BAU as a recently abducted woman, who fits the profile, is a diabetic who will soon die regardless if she does not get her insulin shot. However, another aspect of her being a diabetic may also save her.
