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.

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.

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

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

Luca Manara has been suspended, so he is acting as if he were on vacation, and as if he didn't care about the new crime that has been reported.

Now that Manara is off duty, someone has to take over, and there's an awkward moment at the crime scene. Manara finds himself going to the market with Ada; after all, he has nothing better to do.

Marta meets the victim's family at the bus stop. Fabrizio compliments Marta on her work. Luca is hanging out with Sardi and baby Alice.

Toscani and the team go to see Manara in order to fill him in on the case and try to convince him to give them a hand. They are a long way from solving the case and use the wonderful, common expression in alto mare (at sea, on the high seas) to say this. We also learn something new about Marta Rivera.

Manara can't sit still, and goes to see Ginevra after hours, casting a "casual" glance on the murder victim. Marta and Toscani show the security camera DVDs to Raimondi. Manara goes to the pier to get information from a guy he knows there.

Rivera and Raimondi go looking for Mister Binacci, the victim's friend, with whom he had bought the boat. Manara is there, lurking, and Marta avoids him being seen by Raimondi. Meanwhile, Toscani and Sardi obviously have a secret and don't agree about whether to tell Luca about it.

The squad interrogates Pupi, the murder victim's coworker at the winery. Luca gets to listen in on the interrogation and the ensuing discussions via Toscani's cellphone.

Marta has conversations with both Manara and Raimondi, neither of which is she too happy about. The term innominato or unnamed makes reference to the evil character in Alessandro Manzoni's novel, I Promessi Sposi (The Betrothed).

Manara sneaks up on the winery owner's daughter and the stockroom guy. Toscani and Sardi ask Manara to run an errand, claiming they have 41° C fevers [105.8° F] as a ruse to get him to come over.

Luca goes to see Sardi and Toscani. He opens the door and sees a familiar face he hasn't seen in a while. They go out for some seafood together.

Marta and Ginevra talk about the toxicological report, but also about personal things. Luca and Lara say goodbye to each other, and Luca connects with Stefani's daughter by chance, giving him another opportunity to participate in the investigation.

The questioning continues at the station house. Manara's co-workers are keeping him up to date, in person. But they get an unexpected visit.

Luca gathers some more information about the case when he goes to see Laura's mother. Toscani and Marta go to the place where the DVD was thrown away.

Manara may have been suspended, but that's not keeping him from working on the case in his way. Buttafuoco and Barbagallo go to the dump to find the DVD.

Barbagallo and Buttafuoco find the DVD at the dump, but it doesn't show the clear evidence they were hoping for. Manara is working in the shadows, however, and comes up with something. He calls on Marta for help.

Luca has resolved the case, and Marta arrives with Fabrizio to take over from him. But who could have predicted what happened next?

Marta confides in Ginevra about Luca's declaration of love. Meanwhile, a bus arrives in town, and, as the passengers are getting off, there's a problem. At the same time, Luca is giving Ada a hard time as she drives him to the bus stop to meet his sister.

The investigation gets going. Luca, officially still off duty, had just come to meet his sister at the bus, but naturally, he can't help getting involved in the case, which causes a bit of confusion on the team. Rosmini comes to examine the victim.

Tiziana is confused because she has no clue that she might be a suspect. Raimondi, who shows up with Rivera, is confused because he doesn't realize Tiziana is Luca's sister. Poor Tiziana!

Manara, and Raimondi meet with their chief, Casadio to discuss the case and Manara's status, but the meeting has an unexpected outcome. Meanwhile, the only real suspect is Luca's sister!
