The Falcones are a respected immigrant family living in New York City in 1920. But their peaceful existence is compromised when their cousin, Nilo, arrives after causing several deaths in a fight in Italy. Soon enough, Nilo is wreaking havoc in his new city, falling in with the Italian Mafia and working as a skilled criminal and assasin. Nilo's cousins - Tommy, a cop, and Mario, a preist - do their best to turn a blind eye. But as conflicts in the city begin to erupt into a violent war involving gangsters from all parts of the country, the Falcone brothers may be left with one choice: to join the Mafia themselves.
