Forensics recovers an email that opens up some new avenues in the investigation. Lojacono and Aragona go see the notary at his workplace. Di Nardo's parents want to meet her boyfriend.

In 1906 Vesuvius erupted, its worst eruption of the entire 20th century. Torre del Greco, a town near Vesuvius, was particularly affected. Buildings collapsed, sick people were trapped inside the hospitals, and Giuseppe and Giorgio rushed there to help out.

Pisanelli goes to see Friar Leonardo and remarks how peaceful it is there in the cloister. Lojacono and Aragona go to see the head of Forensics and learn some new details about the evidence.

Giorgio goes to see Cloe perform again, while Giuseppe takes Elena to a place that isn't easy to reach. The two friends are clearly in love.

After work, Aragona and Lojacono walk towards their respective homes together. Aragona says he is home, but is he? Pisanello goes home and makes tea, all the while telling someone (probably his wife?)about his day. Lojacono goes home and gets a phonecall from a certain Sonia...

Moscati continues to disobey the rules of the hospital. Nobody can deny, however, that he is having some success with his methods.

Alex goes to see Nunzia by herself, to see if she can help her, but she gets an unexpected reaction from the girl.

Giuseppe stays late at work, which he is not allowed to do, and he gets an unusual visitor.

Di Nardo and Romano go to see Nunzia's mother. She and her two sons are surprised by the visit and are on the defensive but one name keeps coming up as the policemen question them. At headquarters, Pisanello is studying a series of alleged suicides he is suspicious about.

Giuseppe's passion for his work puts his patients' well-being ahead of following the rules and getting chastised by his superiors. Giorgio is much more easygoing and as soon as the shift is over, is ready to have fun.

Aragona meets up with Marina outside of the workplace and she feels freer to give up some information. Then Lojacono and Aragona go to see the notary again. He is not alone.

Giuseppe walks through the market and witnesses a scene whereby a carabiniere policeman chases down a kid who was trying to steal some food. The kid is one Giuseppe has seen before.

The architect is not happy about his visitors from the police and is on the defensive about Nunzia, the girl. As he is having dinner at his usual spot, Lojacono gets a phone call from the PM.

The evening Giorgio planned to spend with Cloe doesn't turn out as he had hoped. The next day at the hospital, on their first day of work, Giorgio and Giuseppe get to know Sister Helga who rules with an iron fist.

Lojacono and Aragona interview 2 of the notary's employees, while Romano and Di Nardo go back to the mysterious girl's apartment, this time with a warrant.
