Prohibition is a three-part, five-and-a-half-hour documentary film series directed by Ken Burns and Lynn Novick that tells the story of the rise, rule, and fall of the Eighteenth Amendment to the U.S. Constitution and the entire era it encompassed.
The show follows a crime, usually adapted from current headlines, from two separate vantage points. The first half of the show concentrates on the investigation of the crime by the police, the second half follows the prosecution of the crime in court.
A cultured cop-turned-PI probes cases with his brooding, enigmatic pal. Various lady friends also helped the sensitive sleuth, notably a guidance counselor and an ADA.
