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.

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.

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.
