The movie begins in the Atlanta Federal Penitentiary, where an aging prisoner named Joseph Valachi (Charles Bronson) is imprisoned for smuggling heroin. The boss of his crime family, Vito Genovese (Lino Ventura), is imprisoned there as well. Genovese is certain that Valachi is an informant, and gives him the "Kiss of death (mafia)," whereupon Valachi kisses him back.
