Luca and Caterina meet up by chance and and are chatting when Caterina's phone rings. Later, Luca and Marta meet up at Ada's and talk about the case, but not only.

Luca is able to talk to Giulia's father, and then with Giulia herself. He also talks to the people from the newspaper. Marta receives a mysterious phone call.

Tension rises between Marta and Manara. Then Manara gets stopped by the police. It's just routine, but there's a glitch.

Luca gets himself into an embarrassing situation with Marta. But he somehow wriggles out of it with an undercover assignment for her.

Manara's team decides the best way to find out what's going on with Righini and Parri is to go to the post-contest party that evening.

The team is at its best this time. And someone who is usually in the sidelines steps in with prontezza (quick reflexes) and brings this case to a climax.

Giulia Parri and Righini, the editor-in-chief of the newspaper, come in to police headquarters to clear up a couple of things, but then Manara has one of his famous moments of great intuition.

Manara wraps things up, and he does it with kindness. But later, he gets an unexpected visit.

Luca has an embarrassing moment, and worrying, too. But there is a new case to distract him from his problems. This time, a deep sea diver is found dead.

Manara's fumbling with his computer had some potentially disastrous consequences. Meanwhile, the report from forensics is in, and Luca goes to question Giusi — without Rivera.

Luca questions some potential witnesses and suspects. He also takes his personal problem to someone who might have the necessary expertise to help him solve it.

Thanks to Rosmini, Manara gets rid of his symptoms, but not the problem itself. Toscani is under a lot of pressure from his very pregnant wife.

The big question is: Why did Mineo spend so much money on deep diving equipment he couldn't afford?

There's lots going on at police headquarters. Even Caterina shows up at just the right moment.

Everyone is a bit tense for one reason or another. Marta and Luca discuss Miss Vasto, Sardi is having a rough time in her last days of pregnancy, and consequently so is Toscani. But the team is ready to move in on a suspect.
