The murder of 13-year-old Yara Gambirasio shocks the little town of Brembate di Sopra, Italy. To bring the culprit to justice, Prosecutor Letizia Ruggeri only has one tenuous lead — a bit of DNA that is not much help without a database to compare it to. Based on a true story.

A serial killer who’s preying on high-end prostitutes sets his sights on Diana. In a desperate attempt to escape him, she becomes the victim of a car accident that renders her blind and kills the family of 10-year-old Chin. But the killer isn’t done with her, and it’s up to the two survivors to stop him before it’s too late.
