After the exhausting and personally costly aftermath of solving the Darwin Killer case, beautiful and brilliant FBI Supervisory Special Agent Emmie Blanchet was looking forward to a little down time. However, her tranquility is abruptly erased when she is assigned the lead position on an emergency task force created to stop a group of domestic terrorists. With her lover, Joel, the local police captain, and her father at her side, Emmie and her team work feverishly to stop these killers before more innocent lives are lost. When their investigations lead them to the Pavlovian Research Institute, founded by an ex-colleague of Emmie’s father, the team discovers that the perpetrators may, in reality, be victims of mind control themselves. As the plot thickens and becomes more complicated, Emmie and Joel’s relationship and passion grow to new levels, and the pair realize that they want to spend the rest of their lives together. Will Emmie be able to find the source of these crimes and bring the killers to justice? Or will more lives be lost? Will she be able to survive an unimaginable personal loss and still effectively do her job? Will her training and experience help her survive? Or will it be, as Pavlov theorized, that her conditioned responses will guide her?
