With skilled hands and an unnerving eye, Dr Kay Scarpetta tries to unmask a serial killer and prove that her career-making case from 28 years earlier isn't also her undoing.

Following a shocking potential link between the past and present murder investigations, Scarpetta and Marino dive deeper into the present victim's life and the circumstances surrounding her death; Benton's new position with the FBI creates tension when he learns classified information about the victim; Lucy, still grieving the passing of her late wife, uses her technological expertise to help Marino track down the prime suspect, Matt Petersen, who was accused of murdering his wife in 1998.

Scarpetta and Marino visit Matt Petersen at his compound; Lucy and officer Blaise Fruge team up to search for the murder victim's boyfriend; the past investigation takes a turn when Scarpetta is called into the Health Commissioner's office.

In the present, Scarpetta and Benton's marriage is tested when Kay is called in by the FBI to perform autopsies on two dead astronauts. In the past, it's Friday night, and the killer could strike at any moment.
