Young and ambitious prosecutor Julia Vacanti is facing a case that could launch her career. The defendant is David Marquette, a successful Miami surgeon and devoted family man. The victims were Marquette's wife and three small children. His experienced defense team claims paranoid delusions caused by schizophrenia drove him to slaughter his entire family. But the state suspects Marquette's insanity defense is being fabricated to disguise murders that were coldblooded and calculated.
