November 1932. Big-time gangster Joe Palakopolous is playing a dangerous game-- he just had his hitman rub out Danny Kugan, the biggest supplier of Canadian whiskey that Frank Nitti had. And Nitti's plenty sore. Kugan was the only guy who could import Canadian Gold for Nitti. The phony stuff is no good; Nitti quips that bottled rotgut is so bad, ""it peels off the labels from the inside."" Eliot Ness and his men investigate Kugan's killing, and try to find out who will take over the operation.

Chicago, August 29, 1934. That night, in the Haymarket district, special agent Daniel Gosden, a policeman on loan to the Untouchables, goes through a skylight and finds an opium laboratory in the top floor of a rundown tenement hotel. Just then, drug lord Victor Rait and 4 hoods (Gus, Sully, Max, and Trapp) show up, carrying crates of supplies into the place. Rait spots Gosden and gives chase; just as Gosden phones Ness for back-up, Rait blows him away with a shotgun. Then Rait blasts 6 bullets from his gun to disperse the crowd of tenants investigating the noise. Somebody phones the cops, because within minutes Eliot Ness and his men and some policemen are on the scene.

January 1929. Gangster Matt Malloy walks into a sporting goods store; he can't buy an automatic pistol without a police permit, however anyone with $150 can buy a machine-gun. Later, at the Club Montmartre, half a dozen choppers are laid out on Nitti's table. The Council says that now they can move in on the Northside and Bugs Moran. Nitti picks up a chopper and says, ""You got 'em-- use 'em!"" Gang war!

February 1, 1933. Late that night, John ""The Cropper"" Cropsie, the Enforcer for Jules Flack (boss of the Westside combine), stood in the back alley behind the Lido Burlesque house, by the stagedoor entrance-- and pumped some slugs into David Alpine, the key booze supplier for the combine (because he was also selling to the competition). On the night of February 2, Eliot Ness is having Cropsie reenact the crime in front of an eyewitness to the shooting.
