For different reasons, both Lojacono with Laura and Martone with Alex are carrying on their relationships in secret. At Mass, Don Michele asks the congregation to make an effort to help with the investigation into Angela's death.

Alex has a conversation with her father, who hopes for a future for his daughter that will never actually happen. Meanwhile, Pisanelli is increasingly determined to catch the serial killer.

Aragona and Romano go around with the photo they had found, asking questions of guys who might recognize him. At one point, a young man comes out of the bar and starts running, pursued by Aragona.

Lojacono and Di Nardo go to speak with Don Michele again, when Mass is over. The priest confirms that he and Angela cared for each other very much but that they didn't have a relationship. He is being rather defensive, but Lojacono gets him to agree to cooperate.

A parishioner shows up at police headquarters with photos she thinks are compromising. Lojacono and Alex then go to question the volunteers as to whether the insinuations could carry any weight.

Lojacono surprises Laura at dinnertime. Di Nardo has dinner with Rosaria, who has an invitation for her. At the dinner table, Giorgia has something to discuss with Francesco.

The young volunteers talk about how they met and what they were doing the night of the murder. Aragona and Romano come back to headquarters with a photo they found at the victim's home.

Lojacono and DA Piras arrive at the scene of the crime and meet Don Michele. The next morning Lojacono goes with Di Nardo to talk to the kids who had been in the parish hall with the victim.

Lojacono is on a video call with Marina, his daughter, and her friend Chanel, when he gets a phone call from headquarters and goes to a new crime scene, to see what's what.

In a church basement, a priest leads some young people in singing to celebrate the eighty-first birthday of Mariolina. Caterina goes to find Angela, who is late with the cake.

The case has been solved, one gets the feeling that if the murderer had been Varricchio, a common ex-convict, instead of a promising biologist, son of a prominent professor, the outcome would have been more palatable to the city and to the press.

Lojacono is confident he knows how the murder happened and is able to trick Renato into saying something he couldn't have heard on the news.

Lojacono and Di Nardo go to see Biagio's ex-girlfriend to ask her one more question. She happens to remember something that gives them a new lead. They then go and talk to Renato, Biagio's friend and colleague.

Laura and Lojacono go to Laura's house and she begins cooking dinner. At his hotel, Aragona has a chance to see Irene, the new housemaid, in the dining room and can't take his eyes off her. Francesco brings Giorgia breakfast in bed. It's una graffa (a kind of doughnut).

At the hotel where Aragona stays, he tries to find out who the new housekeeping person is. Down at the police station, there is news concerning the prostitute Varricchio says he spent time with the night of the murder.
