Brooke Douger has a knack for helping others with their broken lives, which explains her interest in criminal psychology and profiling. She convinces her childhood friend, Jacob, to move to Tampa after his latest fiasco, where he finds a job at a legal firm, which is defending Zach Barton, a rich, young entrepreneur who is accused of murdering his ex-girlfriend. When Brooke has to provide expert testimony in Barton's trial, Jacob and Brooke end up on opposite sides of the courtroom. As Brooke prepares to testify, she discovers a pattern of violent, impulsive behavior in Barton's past, eerily similar to those of the Surfside Killer, the case she has been asked to help profile for the FBI. Brooke is swirling in dangerous waters with the killer lurking on the fringe of her life. Who will be his next victim? Will Brooke's knack for profiling be enough to keep her safe?
