The truth comes out, and, even though Sianelli is dead, he's able to say something important through pictures.

At the beach party there's a chain reaction (as the title of this episode implies), but this time no dead bodies are involved.

Here we go with a new episode! Lara's enjoying some time off with Massimo, but do we really think it can last? Because, naturalmente, there's a new case to solve.

Personal relations between Luca and Lara may be tenuous, but where work is concerned, they're a great team.

Luca and Lara find Sally at the supermarket and question her. Ginevra explains the results of the autopsy to Luca, but there's still plenty of mystery surrounding this case.

There's a meeting to report new information on the case, and Luca asks a very unusual favor of Lara. You won't want to miss the scene.

Toscani obtains some precious information, but as usual, he's not so quick on the draw to know how important it is. His wife, Sardi, has gotten handy with the software to crack the cell phone. Lara and Luca will be going to two different and unusual places of entertainment in the evening: Luca to a country music motorcycle joint, and Lara to the circus.

Luca, posing as a John Wayne type, goes to the country music bar, and meets up, quite unexpectedly, with someone he had just met the day before.

Let the show begin! We're at the circus, and the ringmaster looks familiar to one of the women in the audience. Meanwhile, Manara has un unexpected encounter as he leaves the nightspot.

A pleasant evening at the circus gets interrupted when Lara gets a phone call and rushes off to the hospital.

Lara keeps her promise to the doctor, but in the process falls victim to some gossip among her colleagues at headquarters.

Based on a true story, this film takes place in Scampia, a poor, crowded suburb just outside Naples. Having one of the highest rates of unemployment in Italy, the Camorra gets its way with many of the kids from this neighborhood, but Gianni also saves many kids by getting them involved in judo.

Melanie, the pretty bartender comes to headquarters with information. She flirts unabashedly with Manara. Lara and her aunt recount the circus show for Manara and a possibly very important detail crops up by chance.

Rubino and Sardi go to visit Marianna at the circus grounds, and Manara has an unpleasant encounter with the motorcyclist's father.

We're taken back to before the shots were fired at the Judo school. We get some background on the school and on Enzo's family.
