In the suburbs of Rome, a small boy disappears, and his mother is found dead nearby. Suspicion falls on the head of the family, but investigator Colomba Caselli doubts that version. Because of past tragic events, she has to investigate the case herself. She meets Dante Torre, an expert in missing persons and child abductions—he is considered a genius, but he has many phobias from his childhood. In this new case of child kidnapping, “the Father” also appears.
