Luca Di Angelo (Fabio Testi) is a smuggler, one member of an organized team trafficking cigarettes and booze up and down the coast off Naples, Italy. After a run-in with the police in which the smugglers manage to get away by faking a boat explosion resulting in the police motorboats responding to the false emergency allowing the smugglers to get away, Luca and his brother Mickey suspect Scherino (Ferdinand Murolo), the head of a rival gang of smugglers, of passing on their actives. Lucia and Mickey take their accusations to their boss Perlante (Saverio Marconi) a sleazy playboy withy numerous Mafia connections, who agrees to look into it. After a nighttime fire at Mickey's racing stables kills a valued racehorse, he and Luca drive over to inspect the damage. But on the way, they are stopped at a fake police roadblock where the assassins dressed as policemen trick Mickey into getting out of the car and machine-gun him to death over and over again (a homage to Sonny Corelone's death scene in The Godfather), while Luca barely escapes injury by hiding on the floor of the car.Afterwards, Perlante suggests that Luca leave town for a few days, but he refuses. After his brother's funeral, conducted on the gang's speedboats in the Bay of Naples, with the police surveying them, Luca vows revenge. Despite his wife Adele's (Ivana Monti) pleas, Luca goes after the prime suspect: Scherino. That night, Luca breaks into Scherino's house, but gets spotted and severely beaten up by Scherino's henchmen. However, Scherino spares Luca's life. He tells Luca that he had no part in Mickey's killing.After Luca recovers from his injuries thanks to a local doctor named Charlie (Giordano Falzoni) who treats injuries for large bribes of cash, Luca meets with an informant who gives him a tip to who ordered the hit on Mickey. Traveling to a derelict fishing boat in the marina where a hood is making a drug pick-up, Luca tortures him for information about his boss, whom Luca learns is a Frenchman called Francois Jacios, aka: The Marsigliese. Luca calls Perlante, who tells him more about the vicious gangster, and who is muscling into Italian organized crime to deal in hard drugs. At his hideout in Naples, the Marsigliese (Marcel Bozzufi) is meeting Ingrid, a German drug courier from Frankfurt wanting to sell him some heroin. When the Marsigliese sees that the heroin is 'cut', he has her face horribly burned by a blowtorch while he watches with sadistic satisfaction.Over the course of one day, the Marsigliese orders a series of shootings of all the rival Mafia Dons all over Naples as part of his plan to become the sole kingpin of Naples. Perlante barely escapes an attempt on his life when his right-hand man Alfredo (Giulio Farnese) triggers a bomb which has been hidden under Perlante's bed, killing Alfredo and Perlante's mistress. Perlante calls Luca and tells him about the series of hits. He sets up a meeting between them and the Marsigliese at the local soccer stadium where the Frenchman discusses merging their criminal concerns. Afterwards, Luca meets with his fellow smugglers and persuades them not to accept the Marsigliese demands for the inflow of drugs into their community would only escalate the number of addicts and drug-overdoses, plus they would not receive any profits since the Marsigliese would keep most of the money for himself and his close associates.In response to the Mafia killings, the Naples police chief (Fabio Jovine) orders Captain Tarantino (Venantino Verantini) to conduct a massive sweep of the Neapolitan bay area to clean it up of crime. The dragnet has many smugglers arrested. Luca is saved from a police raid on his house by, of all people, Scherino, who suggests they form an alliance to defeat the Marsiglise. They meet that night at Perlante's house to discuss their plans with him. But Luca soon smells the tell-tale odor of the Marsiglieses personal parfum in the room. Luca realizes that Perlante is in league with the Marsgliese just as the gangster and his henchmen burst into the room and kill all of Scherino's henchmen as well as mortally wound Scherino himself. Luca's split-second reflexes of diving out a glass window and running away from the house ensures his escape. The mortally wounded Scherino manages to shoot off one shot from his gun at the treaterous Perlante, hitting him in the neck, before he drops dead himself.The Marsigliese abducts Luca's wife, Adale, and again insists that Luca should turn over the smuggling network over to his drug operation. To help Luca make up his mind, the sound of Adale being beaten and gang-raped are relayed to Luca over the phone. Luca agrees to the Marsigliese demands. In desperation, Luca calls upon the elderly Don Morrone (Guido Alberti), the leader of the old-guard Italian Mafia who has been reading the news throughout the movie of the numerous killings. Morrone is happy to come out of semi-retirement to deal with the French sadist. Morrone relays his plans to his various middle-aged associates who swing back into action for their cause.The following morning, a meeting between Luca and the Marsigliese in a local open square where the handover to Adele is taking place. Luca sees that it is indeed a set up to have him killed. Don Morrone and his men, using a series of hit-and-run attacks, appear and blast away all of the Marsigliese's henchmen. Luca then chases the crazed Marsigliese through the deserted streets and allyways where after the Frenchman runs down an alley which is a dead end, Luca catches up to him and shoots the Marsigliese dead who lands on a pile of garbage bags. Across down, the police raid the Marsigliese hideout where they find the tramatized Adele and a large stash of cocaine and heroin, while the rest of the Marsigliese henchmen surrender.The final scene has Captain Tarantino meeting with Don Morrone and his housekeeper at a wharf marketplace where the policeman thanks the elderly Mafia don for his tip leading to the discovery of the Marsigliese hideout and drug shipment seizure. But when Tarantino asks Morrone about the murder of the Marsigliese and his men, Morrone claims to know nothing about it, and also not to know Luca Di Angelo. From Tarantino's sarcastic tone of voice, he knows that Morrone is lying. But out of sympathy, the policeman lets Morrone go without arresting him., Question: Who does Luca call upon?
Output: Answer: Don Morrone
