Martino was left at the train station, but he has to take the bus back to his hometown where he meets up with his friend. A song about wandering plays as he travels: "Vagabondo", sung by Nicola di Bari.

Manara's intuition takes him on a search for a crucial missing element in the case. He tries and fails to explain his thought process to Marta. But together they make some very important discoveries about the suspects.

Martino (guitarist for the famous Italian singer Lorenzo Jovanotti) is having a rough time making his way in the pop music world and coming out of the shadows. Playing well isn't enough, and he isn't getting any help from the lighting crew or his own manager.

The baptism is taking place, and it's clear that Sardi and Toscani have made up with each other. Luca and Marta, however still have some things to clear up. Ada is still hunting for the person who sent her flowers, but she gets a little help from the florist. The party favors, ugly as they are, seem to enlighten Manara about the case.

It's time for the baptismal ceremony. Manara has reason to believe there's something going on between Marta and Fabrizio, and Toscani and Sardi have a tense moment before going into the church.

Sardi and Toscani are nervous about choosing the godparents for little Valeria's baptism. Later, Toscani gets lucky about finding some evidence. When speaking to Raimondi about it, he almost comes out with a colloquial expression but thinks better of it. The complete idiomatic expression would have been una botta di culo [a stroke of the butt]. Culo [ass] is often used to mean "luck," either good or bad. So he had a stroke of luck, or, in modern language, "he got lucky."

They still don't really have a lead, but Manara is convinced the two murders — Viazzi and Ponti — are connected. They have to look into Ponti's past.

The episode revolves around little Valeria's coming baptism. Sardi is able to change Luca's dark mood with a DVD. Ada tries to figure out who sent her flowers, and she also reveals some information obtained while shopping for a baptism gift.

Manara is being closely watched, but that doesn't stop him from doing things his way. Actually, there are two cases to solve.

Manara talks to two different people who knew the murder victim. One comes to him, and the other tries to run away.

Toscani and Manara are at pretty much of a standstill as far as evidence and witnesses go, but Ada says something that makes Manara want her on the team.

Three scenes: An article in the newspaper attracts the squad's attention, Manara questions the maid, and Fabrizio, the inspector, questions Manara.

The murder victim, Mr. Ponti, was on his way to the police station to report a break-in when the crime occurred.

We're at the beginning of a new episode, and we see right away that Luca hasn't hesitated to find some consolation... But he has to rush to police headquarters where there's been a shock for Quattroni. Waiting for him are Raimondi (the new inspector), Rosmini, Rivera, and Toscani.

We recognize the name of the inspector from Rome. Marta recognizes the face. Later, at the farm hotel, Luca is on cloud nine getting ready for a romantic dinner with Marta, until Ada knocks at the door with some news. She milks it for all it's worth.
