Gangsterbaas Colletto (Marcello Mastroianni), ook wel Steenkraag-Charlie genoemd, heeft de mooie hoer Pupa (Sophia Loren) van de straat naar één van zijn nachtclubs gebracht. Hij vindt haar zo opwindend dat hij haar als zijn geliefde aanneemt. Dat is erg vermoeiend voor Pupa, omdat Charlie zeer opvliegend is. Als hij iemand doodt, ziet Pupa een gunstige gelegenheid om van hem af te komen.
Nee, helaas is La pupa del gangster nog niet beschikbaar op Netflix in Nederland.
