A teenage Al Capone joins the Five Points Gang in New York City.
Capone befriends mobster Johhny Torrio, who brings him to Chicago.
I don't feel so good. Eh, it is probably nothing.
Al Capone contracts syphillis while working for Torrio as a bouncer for a brothel.
I've decided that the mob life is too dangerous, so I'm retiring and leaving you in charge!
Torrio retires after surviving an attack by a rivial gang, leaving Capone in charge of a criminal empire.
As a mob boss, Al Capone built an empire, the gang known as the Chicago Outfit, based on bootlegging, violence, and birbery. Al Capone's propensity for violence culminated in the Saint Valentine's Massacre, an attack on Capone's rival gang that left seven dead.
Assistant Attorney General Mabel Willebrandt discovered that mob figures could be convicted of tax evasion without evidence of their other crimes; Capone is charged with and convicted of tax evasion and 5,000 violations of the Prohibition-era Volstead Act.
