A night watchman is killed and the newspaper La Provincia tries to build a scoop, pretending there is a serial killer behind it. However, someone tries to take advantage of it and within a short time the murders of other security guards follow one another. Walter, at odds with the editorial line, decides to investigate.
Unfortunately the movie Trenta Righe per un Delitto: Il Serial Killer dei Metronotte is not yet available on HBO Max.
