Camilla and Susanna are at the marriage agency, when the school principal shows up, without an appointment, to see Dr. Tucci. But Berardi and Torre show up, as well.

Berardi and Torre ask Tucci for information about the victim's dating history, but the person with whom the woman had a date cannot be traced. Susanna admits to being in love with Nico, while Camilla is worried about Renzo.

Renzo finally returns home with bad news. Despite the compliments he received, the highly-connected candidate won. Gaetano, while at home with his girlfriend, receives a message from Camilla, and jealousy takes over.

Torre and Berardi are finishing questioning the man who was hospitalized on the day of the restorer's death, when Camilla arrives. Renzo returns to the office and receives an unwelcome reception from his team.

Gaetano wants to question Susi, and Camilla asks to be present. When her colleague answers a certain question, Camilla is a bit disconcerted. At work, Renzo advises a couple of clients to change architects for reasons of taste.

Camilla goes to see Renzo whose clients have left him, in addition to his assistants. She tries to comfort him without success. Gaetano returns home to his insecure fiancée.

Renzo is still very depressed about work and the blackbird is getting on his nerves. To complete the picture, Camilla's mother shows up and says she will stay with them for a few days.

Gaetano asks Sabrina some questions while Torre and his colleagues recover materials from Tucci's marriage agency. At school, Camilla has the students write an essay about Grimaldi when she notices that something is not right with Celeste.

Susy complains about the fact that Nico has practically disappeared, but Camilla tries to calm her down. At the police station, Romolo's mother attempts to do all the talking. Renzo makes peace with his mother-in-law.

Camilla, Susi, and Mazzeo are leaving school when the police approach because they need to question Moretti again. Despite Camilla being angry with her colleague, she stops to talk with Gaetano to find out how things are going.

At the police station, two women, both clients of Tucci's agency, reconstruct the identikit of the man who robbed them, and a familiar face emerges. Camilla takes Livietta to check about a possible pool for her swimming lessons.

Camilla is offered various options for Livietta's swimming course, but gets distracted looking at a photo and asks the receptionist some questions. Gaetano receives an unexpected visit from his sister, who has a big favor to ask him.

Antonio is a teacher and we find him at Somma Vesuviana, on the slopes of Vesuvius, near Naples. For some time he has tending a small garden, where he grows vegetables, which he sees as miracles of the earth, with seeds developing into fruits.

For many Italians, putting up a presepe (manger scene or crèche) at Christmas time is as, if not more important than putting up a Christmas tree. Antonio talks about the traditions concerning its origins, two thousand and eleven years ago.

Antonio explains that the Italian tradition of constructing a nativity scene during the Christmas season had it origins in the thirteenth century, when Saint Francis of Assisi organized the first live re-enactment of the birth of Jesus. It soon spread to all of Italy, but above all to the Kingdom of Naples, where everyone got involved, from the poorest family to the King himself.
