Sandro remembers that Marcello had confided in him shortly before his death that he had seen Sabatini in the company of a person who could be Bradic. Ardenzi thus begins to suspect Sabatini. While Zaccardo, having learned from the police chiefs that she will be promoted, has decided to offer her position to Claudio. Sabella is called by Cristina in tears because her partner has returned to her and is threatening her. A drug dealer questioned by Ardenzi in prison accuses Sabatini of being corrupt. Darko Bradic's body is found and Ardenzi is increasingly convinced that Sabatini is involved in this chain of crimes.
