Sadistic no-count killer Nanni Vitali and three other equally brutish hoodlums escape from prison. The foul foursome embark on a savage rape, murder, and robbery spree. Vitali even abducts and defiles frightened hapless lass Giuliana Caroli. Meanwhile, rugged police inspector Giulio Santini is determined to bag the despicable Vitali.
Unfortunately the movie The Mad Dog Killer is not yet available on HBO Max.
