Palma and the team have just forty-eight hours to find Varicchio, the father of the two victims. Meanwhile, Palma has to buy furniture, Lojacono meets up with the DA, and Alex comes home late to an angry father.

Alex and Lojacono go to see Biagio's friend and colleague, Renato, and Renato's father, who had been Biagio's professor. Palma talks to his superiors, who want to get involved in the case to speed things along.
