The plot follows the paths of the three characters set in motion by events related to a drug deal gone bad near the Mexican–American border in
Terrell County in Texas. Llewelyn Moss stumbles across the aftermath of a drug deal gone awry that has left all but one dead. That man, barely alive, asks for water. Moss responds that he does not have any, then while searching for other survivors, finds a body some distance off with a satchel containing $2.4 million in cash. He takes the money and returns home, but due to guilt, he returns to the scene with a jug of water. He finds another truck is there waiting. He tries to run, which sparks a chase through a valley. This is the beginning of a hunt for Moss that stretches for most of the novel. Moss sends his wife, Carla Jean, to her grandmother in Texas, while he leaves his home with the money. Sheriff Ed Tom Bell investigates the crime while trying to protect Moss and his wife, with the aid of other law enforcement agents. Bell is haunted by his actions in the
Second World War, for which he received a
Bronze Star. Bell has spent most of his life attempting to make up for an incident when he was a 21-year-old soldier. He makes it his quest to resolve the case and save Moss. Complicating things is the arrival of
Anton Chigurh. Chigurh is a killer whose weapons of choice are a
bolt gun and a pistol. Bounty hunter Carson Wells is also on the trail of the money. Moss, wounded in a firefight with Chigurh, recovers at a hospital while Chigurh patches himself up in a room with supplies taken from a drugstore. Moss is approached by Wells, who offers to give him protection in exchange for the satchel and tells him his location and number. Chigurh finds Wells and murders him just as Moss calls to negotiate the exchange of money. Chigurh tells Moss that he will kill Carla Jean unless he hands over the satchel. Moss remains defiant and calls Carla Jean and tells her that he will meet up with her at a motel in
El Paso. Carla Jean decides to inform Sheriff Bell about the meeting and its location. This call is traced and provides Moss' location to some of his hunters, who kill him but fail to find the money. Sheriff Bell goes to the hospital to identify Moss' body. Chigurh arrives at the scene and retrieves the satchel hidden in an air duct in Moss' room. He returns it to his client and later travels to Carla Jean's house. She pleads for her life and he offers her to
flip a coin to decide her fate, but she refuses. Finally she chooses heads, and the coin turns out to be tails, and Chigurh kills her. When leaving the house, Chigurh is hit by a car, which leaves him injured. He limps off down the road. Bell decides to retire and drives away from the courthouse feeling overmatched and defeated. Bell describes two dreams he experienced after his father died. The first is him meeting his father in town and borrowing some money from him. The second consists of Bell riding his horse through a pass in the mountains. He could see his father up ahead of him carrying a horn lit with fire, and he knew that his father would ride on through the pass and fix a fire out in the dark and cold and that it would be waiting for him when he arrived. He then woke up. == Reception and legacy ==
