De Amerikaanse gangsterbazin Maggie wil met haar maten Jack en Frank de waardevolle kerkschat van San Gennaro buitmaken. De traditionele gigolo Dudu laat zich met moeite overreden om ook mee te doen. Als hij daarop zijn familie inschakelt voor hulp bij de roof, heeft dat verrassende gevolgen.
Nee, helaas is Operazione San Gennaro nog niet beschikbaar op Netflix in Nederland.
