- Narrator: In the years following the passage of the National Prohibition Act of 1920, the nation's underworld rises to power and battles amongst itself, just as modern nations and corporations do. Open periods of gang warfare are followed by peace treaties and attempts at consolidation and monopoly, each of which is shattered as new warfare erupts in quest of the booming bootlegging and vice profits. By 1929, the gangs of Chicago operate 21,207 speakeasies, and their gross income reaches $357 Million. 618 members of the city's underworld are murdered within nine years. Corruption extends from the mayor's office to the humblest side-street speakeasy.
