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.

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

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

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.

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.

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."

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.

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.

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.

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 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 has the proof he needs and goes looking for Pietralonga. An unusual chase scene ensues.

At the bar, Martino sees some old townsmen who tease him and tell him he should get a real job. One of the old guys mentions Fred Bongusto, an Italian singer known for a song "A Rotunda on the Sea". Martino and Peppino go off in a three-wheeled Ape (bee), a light commercial vehicle common all over Italy. Peppino cites Roberto Bolle, a famous Italian dancer, and Men and Women, a TV show for dating.

Manara succeeds in solving the case. But Raimondi is not happy at all and calls Manara into his office.

Martino finally goes home to his mother, and discovers that she watches the show Uomini e Donne (Men and Women) like everyone else, so she knows who Samantha is. Martino calls Laura, or tries to.
