Alberta Tizzani was attacked in her home and helped by her neighbor Marcello; it is he who suggests to the men of the X° Tuscolano that, although the woman claims it was a theft, the culprit could be Cristiano, her husband, a domineering and violent man. Cristiano, however, denies everything.

A woman accuses her ex-husband of beating and raping her, but he denies it and for our men, faced with a web of hatred and lies, it becomes difficult to understand the truth. On the investigation side of the robbery gang, a glimmer of hope seems to open up: it seems that the gang will strike again soon. Our men prepare to surprise them on the spot.

After the disappointment of the failed operation to arrest the members of the robbery gang, a strange phone call takes our heroes to the scene of a murder.

Meanwhile, Alessandro, thanks to a case he stumbles upon, finally faces his grief and returns to Irene's grave.

While Luca follows the trail of Luciano Gerace's (Dante Palladino) Camorra clan, Alessandro, trusting his police instinct, decides to "hook up" Melissa. Meanwhile, the rest of the X° Tuscolano deals with the murder of a mother, in which the main suspect is the woman's stepson. The case is complicated by the fact that the only witness is the lady's biological son, an autistic boy with whom no one seems able to communicate.

While Luca perseveres on the trail of the Camorra, Alessandro (Enrico Silvestrin) continues to see Melissa in secret, putting his life at risk. The case of the episode instead concerns the alleged suicide of a woman no longer young suffering from cancer, whose "last journey" hides a much more disturbing truth.

After risking being killed, Alessandro involves his companions in the search for Melissa, which, in a crescendo of tension, ends with our friends falling into a trap set by the Flaviano brothers. During the episode, the murder of a construction site foreman is also investigated: what at first glance seems to be a simple case of revenge linked to accidental deaths at work, actually hides a much more complex scenario.

Having miraculously escaped the Flaviano attack, our heroes receive a tip from Melissa that leads to the discovery of the weapons used in the robbery in a warehouse in Gerace. The investigations therefore seem to be concluded, but Luca and his team still have doubts.

The inspectors of the 10th Tuscolano are dealing with a case involving a Muslim girl, Khadigia, beaten and repudiated by her husband Yusuf.

In the meantime, Luca and Alessandro, who narrowly missed capturing Giulio Flaviano, are now convinced: there is a mole who informs the criminals of their every move.

Her brother Marco is dead, but Elena can't forgive him for Irene's murder. And while the Flavianos are quietly enjoying the wait to complete the deal with Krueger, our heroes must solve the case of a surgeon accused of uxoricide, who loses his mind and takes Ingargiola and Elena hostage.

From a clue left by the Flavianos in their suite, Luca and his men finally manage to understand the ultimate goal of their plan: to get their hands on an illegal load of coltan, a precious mineral compound.

Thanks to Berti's incursion on Krueger's boat, our guys intercept the agreements between Gerace and the Flavianos, to intervene during the meeting between the boss and the Roman brothers. But first they have to face and solve a case that is close to everyone's heart: the former colleague Parmesan is accused of the murder of a loan shark.
