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.

Luca and Marta question the Bulgarian. Laura Martini suddenly remembers what happened to her on the night of the shooting. The report from ballistics comes through.

Marta and Luca discuss the latest dead end. But what if Mrs. Martini was not the target at all?

The moment has come to discover why Marta was the true target of the attack. And the moment has come for Luca to deal with his unorthodox confiscation of the Bulgarian's gun.

We recognize the name of the inspector from Rome. Marta recognizes the face. Later, at the farm hotel, Luca is on cloud nine getting ready for a romantic dinner with Marta, until Ada knocks at the door with some news. She milks it for all it's worth.
