Dr. Sam Waters (Ally Walker) joins the newly formed Violent Crimes Task Force, led by her mentor, Bailey Malone (Robert Davi), to probe a string of well-publicized arson fires in the South, until her anonymity is shattered -- providing Jack-of-all-trades, her murderous stalker, more clues to her whereabouts. As a result, Sam is forced to move with her daughter (Caitlin Wachs) and her best friend, Angel (Erica Gimpel), while she uses her skills to compose a profile of the self-destructive arsonist (Seth Peterson).
