From the phone records, Imma discovers phone calls received by Bruno but the number doesn't seem to exist. Calogiuri indeed gets a phone call from Paolo in Bari.

The team hears about a new homicide that likely is connected to the first one, so they have to go back to square one, more or less. The forensics expert wonders why Di Nardo doesn't answer her text messages.

Imma is furious about what she reads in the paper, but her boss tells her to calm down and wait for the trial. She also has to deal with a new police officer with a strong personality, but who is also quick-witted.

Lojacono meets his friend Paolo for dinner and they talk about the case in which Lojacono had been falsely accused. The next day, Bukhar is questioned at headquarters.

Lojacono and Aragona go to Ramaglia's house to talk to his wife and daughter. After some questioning, the daughter Rosa remembers someone that might turn out to be important.
