The "stone in the mouth" is the scar that the mafia makes on betrayal's corpse. The modern mafia has the historical and sociological roots into the birth of the american capitalism at the time of Roosevelt. The American "Cosa Nostra" applies the similar methods as the sicilian mafia: same apparatus, same "omertà", same power and same terror. Giuseppe Ferrara, journalist and writer, uses fragments footage, film clips, (Salvatore Giuliano by Franco Rosi, Paisà by Roberto Rossellini) and current news to make this film.
