The true story about the origins of the mafia in America follows Joe Petrosino - nicknamed the "Italian Sherlock Holmes" - an NYPD cop who goes after the ruthless gang in the early 1900s. The thugs (with the calling card black hand) migrated from Italy to America, and kidnapped people to extort money from their families. They were loathed by law-abiding Italian families who were frightened, but nevertheless helped Petrosino behind the scenes.

In real life, Joe Petrosino was a close friend of President Theodore Roosevelt, who was a police commissioner at the time. Coincidentally, Leonardo DiCaprio will later play President "Teddy" Roosevelt, in the upcoming Martin Scorsese directed movie "Roosevelt". See more
