Thirteen-year-old Yara Gambiarasio's body is found, and everybody in her hometown and Italy is in shock; with the help of DNA analysis, the search for the 'unknown male' begins.

A year long court-case ensues; the prosecution presents a scientific case, while Bossetti's defence is based on character; throughout the fraught proceedings, Bossetti maintains his innocence.
