In a studio, Marico and Valeria discover the body of a photographer and near the body they find some red sequins. The investigation leads the two police officers to the home of a young couple, where they find the incriminating sequin dress: the two boys killed the photographer to rob him of a batch of marijuana. In the precinct Valeria realizes that she is not very loved by her colleagues and vents her anger with Giovanna who, in the meantime, has had to reveal to her mother that she is pregnant. The investigation into the Scalise attack continues and the circle tightens ever more around Saro who, having called his girlfriend Laura and given her a date, is followed by the precinct officers. Things between Mauro and Paula do not seem to be improving.
