The protagonist Larry (Woody Harrison Woody Harrelson), a poor kid in Kentucky, grows up to open a porn bar in Cincinnati, but business is not good. At the end of his life, his wife gave him an idea to run a porn magazine to promote his bar, and the "lecherous man" was born. Unlike Playboy, attic and other porn magazines designed for white-collar consumption, Lust Man is a pornographic magazine for the broad masses, and its content is much higher than that of existing porn magazines such as Playboy. It worked. Larry's bar business was booming and magazine sales were on the rise. This aroused fierce opposition from moral conservatives. A man named Keating is desperately suing Larry, and the attack by an unknown gunman paralyzed Larry's lower body. Larry's lawyer Allen (Edward Norton Edward Norton) completely put aside the poison of Larry's behavior to society in court, and focused entirely on the freedom of speech guaranteed by the US Constitution, making this case an important page in American judicial history.
