The prosecutor- Julia Valenciano. Young, ambitious and facing a case that could launch her career. The defendant - David Marquette. A successful Miami surgeon and devoted family man. The victims - Marquette's own wife and three small children. The plea- Not Guilty by Reason of Insanity. But the state suspects Marquette's insanity defence is being fabricated to disguise murders that were cold-blooded and calculated. Worse, Julia believes Marquette could be responsible for a string of unsolved, brutal homicides. The distraught survivor could just be one of the most prolific and elusive serial killers in Florida's history. The trial will take Julia on a painful personal journey back to a past she has struggled for fifteen years to forget. And it will bring her face to face with a future that is so frightening, she's not sure if she even wants to see it.
