The film is adapted from the classic comic of the same name by the famous comic master Frank Miller. It consists of three stories, all of which take place in the virtual Sin City, where there is no difference between the police and the mob. Violence destroys everything and protects everything. Story 1: Sin City The ugly and hot-tempered Ma Fu (played by Mickey Rourke) meets the blonde beauty Goldie. The one-night stand gives Ma Fu the warmth he has never had before. However, after waking up, Ma Fu finds that Goldie lying next to him has been murdered, and he faces the accusation of being the murderer. Ma Fu's heart is ignited by the flames of anger and revenge. With the help of Goldie's sister Wendy, he investigates the truth of the facts and looks for the murderer who killed his lover... Story 2: Sniper Dee White (played by Clive Owen) was a criminal before. After plastic surgery, he became the boyfriend of the bartender Shirley, and helped her teach a lesson to her entangled ex-boyfriend, the violent Jackie (played by Benicio Del Toro). Dee White followed Jackie and his gang to the old town ruled by a gang of prostitutes. Jackie did not follow the rules and was killed by the prostitutes. Later, they found out that Jackie was a policeman. His death destroyed the agreement between the prostitutes and the police. Dee White must help them cover up the crime and protect their rights... Story 3: The yellow bastard Hartigan (Bruce Willis) is about to retire due to heart disease. In the last hour of his police career, Hartigan received information that Roger, the son of a senator, kidnapped the 11-year-old girl Nancy. Roger was the main suspect in several rape and murder cases. He was in great danger. Hartigan rescued Nancy single-handedly, abolished Roger, and was seriously injured. In the following eight years, Roger's senator father used his power to put him in prison and forced him to take the blame for Roger. Hartigan never gave in, and Nancy's letters under the pseudonym Coridia were the only comfort in her life. Nancy's letters suddenly stopped, which made Hartigan very uneasy. He had to give up resistance, plead guilty in exchange for parole, and find ways to protect Nancy. He didn't know that the monster yellow bastard who had been secretly following him would put him and Nancy in danger again...
