Inspector Betti (Maurizio Merli) is transferred to Naples, receiving on his arrival a warm welcome from The Commandante (Barry Sullivan), the city's crime lord. Betti goes on a personal mission against corruption and organized crime, trying to force the syndicate out of town by any means necessary.
Violent Naples was released in Italy on 7 August 1976, where it was distributed by Fida Cinematografica. It had a domestic gross of 2,046,936,220 Italian lire.
The Monthly Film Bulletin described the film as a "nasty, brutish and over-long escapade" that was plagirizing Dirty Harry. The review found thef ilm tobe "lacklustre in style, without a trace of tension to its slam-bang action."
