A series of bizarre murders rocks the beautiful Carpathian town of Brasov. At first there's nothing obvious to link what appear to be random killings.
With the police still smarting from the scandal of having failed to act in a previous case of a serial kidnapper and killer, they bring in forensic pathologist Gigi Alexa to figure out if several murderers are at work - or if they have another serial killer on their hands.
Ambitious, tough, and not one to suffer fools gladly, Gigi fights to be taken seriously in a society that maintains old-fashioned attitudes to the roles of women.
She and the police team struggle to establish a pattern, especially when resources are diverted to investigating a possible terrorist plot. With the clock ticking, Gigi stumbles across what looks to be a far-fetched theory - just as she realises that she could be on the murderer's to-kill list.
