 Sam Waters joins the newly formed Violent Crimes Task Force (VCTF), based in Atlanta and led by her mentor, Bailey Malone, and assisted by detectives John Grant and Nathan Brubaker, forensic specialist Grace Alvarez, and computer hacker George Fraley, to probe a string of well-publicized arson fires in the Deep South, until her anonymity is shattered by her murderous, unseen stalker, Jack-of-All-Trades. As a result, Sam is forced to move with her daughter Chloe and her best friend, Angel, away from their country house, while she uses her skills to compose a profile of the self-destructive arsonist before he strikes again.
