Sin City (2005)
On the docks of Sin City, aging police officer John Hartigan tries to stop serial child-killer Roark Junior from raping and killing his fourth known victim, eleven-year-old Nancy Callahan. Junior is the son of Senator Roark, who has bribed the police to cover up his son’s crimes. When Hartigan’s corrupt partner, Bob, tries to convince Hartigan to walk away, Hartigan knocks him out.
Hartigan, experiencing pain from a bad heart, heads into the warehouse where Roark Junior and several henchmen are holding Nancy. Junior shoots Hartigan in the shoulder and tries to escape. Hartigan catches up and shoots off Junior’s ear, hand and genitals. Bob, now recovered, shoots Hartigan in the back. As the sirens approach, Bob leaves and Nancy lies down in Hartigan’s lap. Hartigan passes out, reasoning his death is a fair trade for the girl’s life.
Hartigan is recovering in a hospital when Senator Roark informs him that Junior is in a coma and the Roark legacy is in serious jeopardy. Hartigan will be framed for Junior’s crimes; if he tells anyone the truth, they will die. A grateful Nancy promises to write letters every week while he is in prison. Hartigan goes to jail, though he refuses to confess. He receives a weekly letter from Nancy, as promised. After eight years, the letters stop and he receives a severed finger instead. Hartigan confesses to all charges leading to his parole and searches for an adult Nancy, not knowing he is being followed by a deformed, yellow man. He eventually finds her at Kadie’s Bar, where she has become an exotic dancer.
He realizes he was set up to lead the yellow man to Nancy and the two escape in Nancy’s car. Hiding in the trunk of Hartigan’s car, the deformed man returns, revealing himself as Roark Junior, disfigured by years of surgery to regenerate his body parts. Junior attacks Hartigan and takes Nancy to the Roark farm to finish what he started eight years before. Hartigan follows and fakes a heart attack, giving him a chance to kill Junior by emasculating him and beating him to death. Knowing that Senator Roark will never stop hunting them, Hartigan commits suicide to ensure Nancy’s safety. Again, he justifies his life for Nancy’s as a fair trade.
