A mysterious killer kills a young woman staying at an institute for the blind. The suspicions of the inspectors of the X Tuscolano focus on the director and owner of the institute, the only beneficiary of the insurance policy taken out by the woman before her death, but the testimony of a friend of the victim who smelled the killer will lead the investigators on the right track. Contrary to Commissioner Benvenuti's orders, Inspector Anna Gori thwarts the raid on the Russian mafia's weapons depot and saves Dorian. Having gained his trust, she manages to attend the meeting of the organization's leaders and photograph them, but realizes she is being spied on.
