 Douglas Fairbanks Jr. and Peter Fonda host an examination of the history of decency standards for movies, starting in 1922 with the hiring of Will Hays. When studios ignored the code early in the Depression, Catholics established the Legion of Decency, Hays hired Joseph Breen, and the code got muscle, with an impact on films as diverse as "King Kong" and "The Little Princess." Jane Russell and others discuss the code, cleavage, and the bullet bra in the 1950s. Baker and Wallach comment on the "Baby Doll" controversy. In the late 1960s comes a new classification system. Scorsese discusses it s application to "Taxi Driver." A look at "Carnal Knowledge" follows.
