Gangster Vic Smith is deported from the United States to Italy, where he was born under the name Vittorio Mario Sparducci. After arriving by ship in Naples, Vic is met by Vito Bucelli, an Italian policeman, who informs the gangster that he must leave that afternoon for his home town of Marbella, where he is required to remain for the next thirty days. As he enters a taxicab, Vic meets Gina Carapia, a beautiful young woman who lures him into a trap set by his old henchman, Bernardo Gervaso. Gervaso demands his "cut" of the $100,000 Vic was convicted of stealing, but Vic insists that he left the money behind in America, and, having served five years in prison as well as being deported for the theft, feels he is entitled to the entire sum. Vic then beats up Gervaso and orders him to stay away. In Marbella, Vic is treated to a hero's welcome, as the townspeople are under the impression that he is a "local boy who made good," and is returning to Italy after completing a mysterious government mission. His uncle, Armando, goes so far as to insist that Vic come to live with him and his family. Soon thereafter, Vic becomes involved with Countess Christine di Lorenzi, a wealthy widow who is responsible for the distribution of American relief supplies to the town's poor. Vic then hatches a plan with Guido Caruso, the head of the local black market, to use his hidden money in America to buy massive amounts of relief supplies, then hijack the shipment and sell the much-needed food and medicine on the black market. When the relief supplies arrive, a great festival is held, and Christine tells the townspeople that Vic is their benefactor. Despite feeling pangs of guilt, Vic still plans to steal the relief supplies until the unexpected appearance of Bucelli, who has come to Marbella to check up on Vic. Afraid that the policeman will rightfully blame him for the hijacking, Vic insists that Caruso call off the heist, but the black marketeer insists on going ahead with the plan. As Caruso and his men enter the warehouse holding the relief materials, Vic is waiting for them and quickly captures Caruso, only to be captured himself by Gervaso, who has recently joined Caruso's gang. Vic is saved, however, by the arrival of Bucelli and the police, who capture Caruso and his gang after a fierce battle. Gervaso is then killed while fighting with Vic after he accidentally overturns a pile of packing cases on top of himself. The next morning, Vic and Bucelli head for the railroad station, as Vic has been summoned to Rome to explain his involvement with Caruso. Christine joins them on board the train, announcing that she is in love with Vic, and despite knowing all about his past, is willing to stand by him in court.
