In 1951, two years after the “scandal” of the Fiamma che non si spegne, Cottafavi got the opportunity to work on a film with a small production company, Novissima Film. With little means, a number of technical and financial problems and working Sundays with the pieces of film given to him bit by bit, Cottafavi shot Una donna ha ucciso, a minor film that marked his comeback to directing. (Gianni Rondolino)

Inspired to the real story of the Carabiniere Salvo D'Acquisto. We see how, to save 22 hostages from dead sentence by Nazi, he decided to sacrifice himself.
