Imma is back in the office when she gets an unexpected visitor.

Some evidence has been burned in what appears to be a gas leak, and Imma is very concerned for her case against Romaniello. She goes back to her office to fight back when she has two different visitors, one more welcome than the other.

Imma meets her colleagues at the crime scene and recognizes the victim. The marshal of the Pisticci Carabinieri also knew the young woman who apparently had taken her own life.

Imma is offering her condolences to the parents of the victim, while gently questioning them. At the same time, she thinks back to a conversation she had had with Donata.

Grandma and granddaughter prepare a traditional dish from Basilicata, called la ciambotta, a kind of stew with vegetables, and sometimes meat. Valentina serves it to her parents that evening. The next day, Imma and Diana talk about the parliamentarian, Lombardi.

Imma talks to the proprietor of the restaurant where Donata was to try out as a waitress. She also has a more fruitful conversation with an employee. Later on, she takes her mother to the eye doctor, where she gets somewhat of a jolt.

Imma takes her mother to the eye doctor and by chance absorbs some new information about her past. She talks about the Romaniello case with Vitali and lets him know she will be gone for a couple of days.

Imma has decided to go to Rome on her own dime to try to talk to Lombardi. Pietro isn't convinced about her motivation. The bus trip isn't very comfortable.

Imma arrives in Rome and gets on a motor scooter for the first time. She and Calogiuri discuss the murder case and then Imma goes to talk to Lombardi.

Imma manages to exchange a few words with Congressman Lombardi as he waits to go and vote in the Chamber. She lets him know that Donata's death might not be a suicide.

After speaking with Lombardi, Imma meets up with Calogiuri again to discuss things and he gives her an update on his social media encounter with Lolita. Pietro goes to a sax lesson at the home of his teacher.

Imma and Calogiuri are enjoying dinner together, but the conversation is a bit awkward. A guy comes by selling roses, creating yet another awkward moment.
