This crime story is set in the city of Matera in the Basilicata region, where Immacolata (Imma) Tataranni is the deputy prosecutor. She's on vacation at the beach when she finds something odd in the water.

Imma tells her husband about the finger she saw, but he seems skeptical. She is none too happy about her daughter's bathing suit, and also gives the barman a hard time.

Imma goes back to the office, stopping to chat with the cleaning lady as she makes her way upstairs. She meets the new chief prosecutor.

Calogiuri and Imma go to the site, where they are making a movie, to see if there is anything to be learned. Calogiuri gets noticed by the director because of his good looks. Could he make it as actor?

We get a glimpse of Imma as a parent. She is not so convinced about the value of cellphones. And she doesn't get along so well with her mother-in-law, either.

Calogiuri goes to talk to Imma at the beach. His presence doesn't go unnoticed to the young girls. Imma goes to see the new chief prosecutor.

Imma and Calogiuri go to the water park where they talk to the coroner. Calogiuri proves to be pretty smart and earns some praise from Imma.

Imma and Calogiuri go to see a woman who had her finger cut off. Calogiuri offers to take Imma back to Metaponto.

Imma is finally home, ready to have something to eat and discusses this on the phone with her husband. But then he urges her to turn on the local news station, quick.

Imma chases down her mother who is very mixed up about where she lives. She goes to the morgue to talk to the coroner about the new body part that was found.

Tataranni and Calogiuri talk to the owners of the dairy farm where the victim's limb had been found. On the way back, Calogiuri gets a good idea.

Imma buys a dress to replace the one with a stain. Calogiuri has some new information about the victim. Meanwhile, the chief prosecutor gets a disturbing email.

Imma discovers that Aida used to go to the same club where her daughter, Valentina, is at a party. She does what she feels she has to do.

Not surprisingly, Valentina is furious with her mother. Imma and Calogiuro go back to the beach to question Vaccaro. Not surprisingly, he has no idea who Aida Bashir is.

Vaccaro's memory is jogged. He mentions the actor in the movie they're making nearby, so Imma and Calogiuri go to the set to have an informal conversation with Sergio Covaser who is on his lunch break.

After talking to Sergio Covaser, Imma and Calogiuri have an idea of who he is. Imma is concerned about her daughter and talks things over with her husband.

Imma gets some anonymous information that leads her to more remains. Putting their heads together, Imma and Calogiuri connect some dots, both on a map and figuratively.

Imma happens to know the judge who was involved in the judicial auctions Calogiuri had found out about. She and Pietro get together with him for a friendly lunch in the country.

Calogiuri has done some research about the Paradise Farm, run by Saverio Romaniello's non-profit organization. Imma makes a surprise visit to Romaniello and subtly lets him know how much she knows about him.

During the bus ride, Imma sees someone with a familiar-looking tattoo and finds out where it came from. They arrive at Pietro's mother's house, where they need to make introductions, since Imma's mother doesn't recognize anyone.

Imma gets some important information from the beautician. Back at her in-laws' house, Imma tries to remove the tattoo, and Pietro is helping his mother in the kitchen. Calogiuri calls with some new information, which Imma wants to act on right away.

Imma convinces Nunzia to talk. And she has plenty to say. Imma and Calogiuri discuss the case as they go to the supermarket for groceries, since the next day, all the shops will be closed.

It's the eve of Ferragosto, the big August holiday. Imma has her mind on work, but in the midst of the dinner table chatter, she turns her attention to her daughter, Valentina, who is still not speaking to her.

Thanks to Imma and her team, Staffieri is arrested. Romaniello goes to Nunzia's house with Imma to ask forgiveness.

Leila can barely open her eyes or speak, but she understands what Imma is asking her, and manages to tell her about what happened to Aida.

Leila's story identified the killer but can't be used as evidence. Imma and Calogiuri go to the beach club to look for Vaccaro.

Imma calls Romaniello in and tells him her version of the story.

Romaniello opens up to Imma and shows his true colors. Imma takes her mom home, but the apartment seems unfamiliar to her with its modern conveniences like a TV, and running water.

Imma is back in the office and so is her talkative assistant, Diana. Imma's boss comes in with some papers. Who knows? Now that summer is almost over, maybe Imma will find some time to relax.

We begin a new episode, where Valentina is at school, learning about politics and toxic waste.

Imma goes to where the dead body of Nunzio Festa had been found. She has to deal with the local Carabinieri marshal, who is a bit of a bully. She and Calogiuri go to see the parents of the deceased.

Imma and Calogiuri rummage around in Nunzio's room, and Imma sees a photo: Nunzio's girlfriend. So they go to see her next after asking Nunzio's stepmother some questions.

Imma, Valentina, and Pietro discuss the event of the day and whether or not Valentina can go to the concert. Imma goes to talk to La Macchia about Carmine Amoroso.

Imma has to find a new home-health aide for her mother. Diana is on Imma's back about the class reunion. La Macchia shows up at her office in a huff about Calogiuri. But there's also some good news. Lab analyses have resulted in some new evidence.

Imma and Calogiuri go to see Nunzio Festa's father to find out more about his son. Signor Festa doesn't know a whole lot, but remembers a strange guy Nunzio hung out with sometimes. A certain Manolo is next on their list of people to see.

Imma has a chat with Manolo about Nunzio, who had worked for him for a time. Later, Imma catches up with Milena and tries to get some more information from her.

Imma comes home. Pietro is practicing his sax. Valentina shows up in a rage. Then Imma is reminded of the class reunion dinner... the last thing she wanted to do.

Imma is not exactly enjoying herself at the party, but she does notice something interesting, and possibly pertinent to her case. She encounters the deskmate who replaced Diana way back then.

Imma goes to see her friend Pino at the museum to ask him about the fragments she saw at the reunion. She then goes to the cemetery with her mother.

Imma is in the courtroom trying to get Saverio (from the previous episode) indicted. Later, she meets up with Calogiuri at the office, but there is someone else waiting for her.

Poor Pietro is having trouble discussing family problems with Imma, because she is easily distracted by the case she is trying to solve. At the office the next day, she has to deal with her colleagues, something she finds distasteful, and doesn't hide very well.

Milena comes to Imma's office and tells her what she knows. She also makes an effort to remember a detail that might be important to the case.

Imma, Milena and Calogiuri go to the woods where Nunzio had seen the porcupine. Later they have a meeting with La Macchia in Imma's office.

It could be that Imma has found a solution for her mother. Pietro has prepared a delicious dinner, but whether or not his family will be able to enjoy it remains to be seen.

Imma interviews Manolo and learns some interesting new facts. Then she interviews the person Manolo mentioned, someone she has encountered before. This second interview is trickier, and Imma has a hard time.

Marshal La Macchia reports his findings to Imma. Later, she goes to see Father Mariani to discuss an old case that has come to mind.

Father Mariani is not much help to Imma, but tells her to be careful. When she gets home, she gets a taste of what he meant, but is not deterred. Imma seems to be of the opinion that "when the going gets tough, the tough get going."

Antonio Palma has been summoned by Imma, and has been accompanied by Rosario Festa, Nunzio's father. She has some specific questions to ask Mr. Palma, but first has a conversation with Rosario Festa. Later on, she discusses all this with Calogiuri over coffee.
