Things are hopping. Luca and Toscani go out to the scuba diving test in a speedboat. Rivera, left alone at police headquarters, has to take matters into her own hands when she answers Toscani's phone.

Carlo introduces us to his teacher assistants, and as its Christmastime, they're wearing Santa-inspired costumes. Alessandra and Massimiliano are the two contestants.

Toscani and Sardi seem to be getting along better. At police headquarters, some very interesting news crops up, and Luca realizes what he has to do.

Luca and Giusi go diving for the amphorae. Rivera forgets her place and tells Luca what she thinks.

Luca and Marta learn that the amphorae were never actually found. Luca enlists the help of Giusy Vasto to try and find them while trying to get more information from her. Marta isn't thrilled about this.

The police are armed, in position, and ready to move. Their mark shows up, and the money is on the table. Then things get dicey.

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.

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

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

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.

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.

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

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.
