"The Deuce" follows the rise of the porn culture in New York from the early 1970s through the mid-1980s, exploring the rough-and-tumble world of the sex trade from the moment when both a liberalizing cultural revolution in American sexuality and new legal definitions of obscenity created a billion-dollar industry that is now an elemental component of the American cultural landscape. Beginning in 1971, the show follows a cast of barkeeps, prostitutes, pimps, police and nightlife denizens as they swirl through a world of sex, crime, high times and violence and the porn business begins its climb from Mafia-backed massage parlors and film labs to legitimacy and cultural permanence.
