It's a busy day for the police. A prime witness ends up in the emergency room at the hospital, and there have been three burglaries, one after another.

A romantic moment gets rudely interrupted by another murder. But do Luca and Lara have the same idea about living together?

Even though the case has been solved, Luca gets yelled at by Casadio. To understand their parting words, there's an idiomatic expression to learn. Chi va con lo zoppo impara a zoppicare (He who goes around with a lame person learns to limp). A similar expression in English is "bad company brings bad habits."

The truth surfaces, and we see a flashback of the fatal event. It's a painful moment for everyone involved.

The race ends, and Manara discovers what he came to find out. He also discovers that Lara is a very capable cop.

As expected Manara's boss doesn't give him permission to infiltrate the race. Do you think that will stop him?

Luca questions Lupo, and figures out how to find out for sure who murdered Gabriele, but as usual, he's immune to warnings about how dangerous it will be.

There's some girl talk between Lara and Sardi, Luca is not a great dinner guest, and Buttafuoco and Barbagallo make an interesting discovery.

Luca's charm works like a charm and he's able to obtain the information he needs from the woman in the motorcycle shop.

Luca confides in Toscani who is, however, not very encouraging on the subject of marriage. Lara calls with some information, and Luca goes back to question Lupo.

Rubino and Sardi go to question Elena, Gabriele's ex-girlfriend, while Manara questions Elena's current boyfriend.

Lara and Luca have been skirting the marriage issue, but they do finally talk about it, albeit briefly. Meanwhile, they get some new information about the case.

Toscani, Lara, and Luca are working on the case, but Toscani is clearly distracted. Luca tries to get some information from Gabriele's rival.

Ada provides Luca with some welcome company, food, and gossip. Ginevra communicates the cause of death, while Luca and Lara toss around a couple of different possible hypotheses surrounding the motorcyclist.

Luca and Lara are doing the best they can to work on the case despite their inner turmoil. Luca's sister wants to help him, but there's a limit to what she can do.

Lara and Luca go into work mode automatically, to try and solve this new, upsetting case, but they each have private, unhappy thoughts that keep turning around.

By popular request, Manara is back with some new adventures. Everything is in place for a joyous celebration, with wedding bells, but is it too good to be true?

A beach party concludes this episode, and season. Love is in the air!

Emotions are running high in this segment and we're hoping that Lara gets found, and that she's alive.

The tension is almost unbearable for everyone. But when the going gets tough, the tough get going.

We get a taste of what life is like at police headquarters without Luca. We also see that Lara learned some bad habits from Luca, going off on her own on a hunch.

There are plenty of people—women, actually— to send Luca off on his bus, but he keeps looking around for a certain someone to show up...

It's time for Luca to say goodbye to his colleagues and friends. It's a sad moment for everyone.

In this segment, we see a flashback to Iolanda's murder. She was an honest woman through and through. And it looks like Manara confirms his resignation, now that the case has been solved.
