A lawyer dies opening a parcel bomb addressed to her and immediately after a man warns the police that two other people will pay for what they have done in the past. The video from the luggage storage room shows Clara picking up her suitcase and forgetting her sunglasses on the counter: Carlo and Malik think she did it on purpose to provide a lead to anyone who was on her trail, but the clue seems to lead nowhere.

Cantabella and Pugliani, accompanied by the still nameless man who waited for Clara when she left prison, arrive at an abandoned warehouse to recover the drug load. Carlo, Malik and Trevi believe they are on their trail, but they soon discover they have fallen into a trap.

Alba, her sister Alice and Federico arrive at the scene where Clara's lifeless body was found; Malik, who begins to suspect the boy, decides to investigate him. In the meantime, a young man with obvious signs of beating shows up at the police station but dies in Bragadin's arms before he can file a complaint. The investigations into the body of Pugliani's accomplice, Calzola, lead to a mysterious safety deposit box.
