Laundrette delivery boy Davide collapses from a fatal overdose cardiac medicine while delivering Bruneti's wife's laundry. Devout mother Ana Cavanella, whose sister Maria Pia runs the salon, confesses having helped mentally handicapped Davide committing suicide. Yet the Brunettis aren't convinced the case is that simple, given evidence of his taste for life and creative talent. Paolo gets into trouble by perjuring herself to counter an order from above trough Patta, who is presently obsessed with a profiling author's book he was invited to write an introduction for, to close the case. After an autopsy, nearly prevented by untimely cremation, shows the tablets weren't just Ana's, Guido digs into the family's past and links it to the attempts to stifle his investigation, leading to disabled copper magnate Ludovico Lembo and his wife Ginevra. The doctor who prescribed the tablets is murdered.
