In a penthouse on the roof of a skyscraper overlooking Basin City, a fancy party is in progress. A woman (Marley Shelton), dressed in a red evening gown, is alone on the balcony. A man (Josh Hartnett), who is narrating, walks up behind her and offers her a cigarette. They exchange some small talk, he tells her that he sees in her eyes a “crazy calm”, of someone who is tired of running, but doesn’t want to face her problems alone. He tells her that he will save her, and take her far away. They kiss, then he shoots her. She dies in his arms. He says that he does not know who she was running from, but will “cash her check in the morning.”
In the DVD commentary, Frank Miller explains that the victim in this story (the Customer of the title) is actually committing suicide. The unnamed woman had dated a mobster, and when she tried to break it off, he said that he would kill her in the most terrible way possible. She then used her connections to hire a hitman (known as the Salesman) to provide her with a quick death.
On the docks of Sin City, aging police officer John Hartigan (Bruce Willis) is attempting to stop serial child murderer Roark Junior (Nick Stahl) from raping and killing 11-year-old Nancy Callahan (Makenzie Vega). Junior is the son of the powerful Senator Roark (Powers Boothe), who has paid off many police to cover up his son’s crimes, including Hartigan’s partner Bob (Michael Madsen). Bob tries to convince Hartigan to walk away, and appears to succeed, but Hartigan sucker-punches him, knocking him out cold. Hartigan then makes his way into a warehouse, knocking unconscious two local criminals. Junior is inside with the frightened Nancy and two armed henchmen, who are making sure that Junior and Nancy “get along” before leaving them alone. Hartigan shoots and kills the henchmen, but Junior shoots Hartigan in the shoulder, grabs Nancy and runs out to the docks. Hartigan catches up to Junior and shoots off his ear, causing him to drop Nancy. He then shoots off Junior’s hand and genitals, before being shot in the back several times by Bob, who has recovered. Bob tells Hartigan to stay down, but Hartigan knows he must buy time for backup to arrive (as Bob will kill Nancy if they are alone) so he tries to pull his reserve gun, causing Bob to shoot him several more times. As the sirens approach, Hartigan lapses into unconsciousness knowing that Nancy is safe, justifying himself with the words “An old man dies, a little girl lives; fair trade.”
An injured Becky departs from a hospital, talking on a cell phone with her mother. While riding in the elevator, she is met by the Salesman. Stunned, Becky hangs up the phone. The Salesman offers Becky a cigarette, implying that he was going to kill her, since he also offered the customer from Act 1 a cigarette, but it cuts to black before anything is done.
