Giulia informs her sister of what happened to Paolo and, without giving herself peace, tries to find an explanation. Her colleagues advise her to take at least a day off. Meanwhile, Vittoria finds herself dealing with the case of Simone, a deaf-mute child who would like to attend a normal school. In addition, a sixteen-year-old is found dead in the courtyard of his school and Luca and Corrado begin to investigate. Thieves enter Mauro and Germana's house and steal the video camera with which Inspector Belli had filmed Giulia and Paolo's wedding day. Mauro cannot stand the idea of having lost that precious tape and launches into investigations. Luca and Corrado, on the other hand, try to solve a difficult case whose victim is a young woman, a chat lover, who is found suffocated in her home. Meanwhile, Vittoria and Ingargiola seem to be jealous of each other and Ardenzi receives a letter from Francesca.
