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.

Luca questions young Guglielmo and gets the answers he needs. He is less satisfied with the conversation with Giusi Vasto. Rivera listens to it all.

There's a new member of the Toscani family, Sardi apologizes to Marta for her behavior, and Ada confides in Luca about a discovery she has made.

There is reason for celebrating the end of the case and the return of the amphorae. But Manara gets some more information about inspector Rivera and has a hard time letting things go.

This new episode starts off with a bang (pun intended). We also get a glimpse of what home life is like, now that Sardi has brought her baby home from the hospital.

The investigation has begun. The girl who was shot is still alive. Luca apologizes to Marta, and Marta gets a mysterious phone call. Toscani has a hard time staying awake.

Manara and Toscani go to the cheese factory. They don't find the answers they are looking for, but think someone there wants to talk. Marta asks for a little time off to go to her appointment.

We still don't know much about Marta Rivera's mysterious appointment, just that it was with the chief. A worker from the cheese factory shows up at the police station to give her statement.

Manara goes to see Casadio, asking for something he knows will be refused to him. He is actually in search of information on Rivera's earlier visit there. Buttafuoco and Barbagallo seem to think there is going to be a surprise party, since an assortment of cheeses was delivered to the police station.

Luca goes to see signora Martini in the hospital. When he gets back to the police station there is a secret ballot going on. Caterina shows up at the end.

Caterina talks to Luca in his office. Toscani brings a fax that looks more like a newspaper or a bed sheet, it's so long. Luca hatches a plan that involves Ada, Toscani, and himself. Ada's new guest seems to like her!

Manara and Toscani go on a secret mission. Luca takes a lot of risks, but gets some important information. Toscani catches up on some much-needed sleep.

After his night trying to outwit the dogs, Manara is not thrilled with Toscani. Ada gets flowers, and Marta gets a phone call.

Some officers slept through the night, others didn't, and this creates some tension at the police station. The mysterious truck driver is identified, and the analysis results of the milk used by the Soleri company to make cheese have come in.

The police squad goes to the Dairy to arrest Mister Soleri, and Manara hunts down Ivan Iordan.
