Al Pacino. Plot In 1920s Chicago, Italian immigrant and notorious thug Antonio "Tony" Camonte works as a bodyguard for crime lord "Big" Louis Costillo. Siding with Costillo's disgruntled lieutenant John "Johnny" Lovo, Tony guns down his boss. Lovo takes over Costillo's territory in the South Side and has Tony and his associates, Angelo and Guino "Little Boy" Rinaldo, set up a lucrative bootlegging operation selling illegal beer to all of the bars there. Tony urges Lovo to start moving in on the North Side, where the bootlegging is controlled by the Irish gangs of gangster O'Hara; Lovo refuses, ordering Tony to leave the North Side alone. Tony ignores these orders and starts attacking O'Hara's businesses while expanding his rackets to the North. Before long, Lovo is forced out of his position as Tony wins over their gang with his success. Meanwhile, Tony pursues Johnny's girlfriend Poppy. At first, she is dismissive of him, but pays him more attention as his reputation rises and he starts flaunting his wealth. She visits his "gaudy" apartment where he shows her his view of an electric billboard advertising Cook's Tours, which features the slogan which inspires him: "The World Is Yours". Tony finally gets rid of O'Hara by having Guino assassinate him. O'Hara's successor, Tom Gaffney, declares war on the South Side and attempts to kill Tony in a restaurant with tommy guns – which an excited Tony quickly arms his own men with. The war results in Gaffney's gang being killed off one by one until he's forced to go into hiding. A group of prominent citizens, including the police chief, vow to bring Tony down for all the carnage and bloodshed he has inflicted on the city. During a night out at the theater, Tony learns that Gaffney and his entourage are at a nearby bowling alley. Leaving Angelo behind to watch the rest of the show, Tony personally kills Gaffney. Lovo's anger at Tony finally boils over when Tony openly flirts and dances with Poppy in front of him at dinner. Tony sees his beloved sister Francesca "Cesca" dancing with a stranger and takes her to his mother's home by force before hitting and yelling at her. A crew of gunmen later try to assassinate him, but he runs them off the road with his bulletproof car. Suspecting Lovo's involvement, Tony goes to his office after bribing one of Lovo's men
