The film Sin City sets about on a balcony overlooking the highlights of Basin City, a grimy, violent and corrupted place. The Customer (Shelton) is greeted by The Salesman (Hartnett), who offers her a cigarette before mysteriously killing her. From there the film moves to the the docks of Sin City, where it is seen that the aging police officer John Hartigan is keeping no stone unturned to prevent the heinous child molester Roark Junior from raping the eleven year old minor child Nancy Cakllahan. At the initial stage his closest ally Bob tries in all measures to stop him, but finding no other way out to prevent Hartigan punches him in the face, knocking him out cold. This is followed by the face off of Hartigan with the dreaded local criminals Shlubb and Klump, whereupon he knocks them both out. When he finds Junior he succeeds in shooting off his ear, arm and shoots him in the groin before being shot 3 times in the back by Bob. Bob tells Hartigan to stay down, but Hartigan tries to pull his reserve gun and is shot again by Bob another 5 times before he leaves Hartigan there with Nancy. The film moving through the respective three parts reaches the climax where Hartigan explains his secret plans required to reveal the corruption of Senator Roark to the administration and finally bring down the corruption in Sin City. But after the depart of Nancy, Hartigan revealing that this would be an impossible task commits suicide in order to ensure Nancy's safety. In the epilogue, an injured Becky is seen departing from a hospital. While riding in the elevator, she is discovered by the Salesman, who offers her a cigarette.
