Robert McCall finds himself at home in Southern Italy but he discovers his friends are under the control of local crime bosses. As events turn deadly, McCall knows what he has to do: become his friends' protector by taking on the mafia.
In the immediate post-war period, amidst the rubble of a poverty-ridden Naples, two kids, Carmine and Celestina, try to survive as best they can by helping each other out. One night, they secretly board a ship bound for New York to reach Celestina’s sister, who emigrated to America several years earlier. The two children join the many Italian emigrants seeking a new life in America and arrive in an unknown metropolis, which, after several misadventures, they will learn to call home.
