Story:
West Texas in June 1980 is desolate, wide open country, and Ed Tom Bell (Tommy Lee Jones) laments the increasing violence in a region where he, like his father and grandfather before him, has risen to the office of sheriff.
Llewelyn Moss (Josh Brolin), hunting pronghorn, comes across the aftermath of a drug deal gone awry: several dead men and dogs, a wounded Mexican begging for water, and two million dollars in a satchel that he takes to his trailer home. Late that night, he returns with water for the dying man, but is chased away by two men in a truck and loses his vehicle. When he gets back home he grabs the cash, sends his wife Carla Jean (Kelly Macdonald) to her mother's, and makes his way to a motel in the next county,[5] where he hides the satchel in the air vent of his room.
Hitman Anton Chigurh (Javier Bardem) has been hired to recover the money. He has already strangled a sheriff's deputy to escape custody and stolen a car by using a captive bolt pistol to kill the driver. Now he carries a receiver that traces the money via a transponder concealed inside the satchel to Moss's hideout. Bursting into the room at night, Chigurh surprises a group of Mexicans set to ambush Moss and murders them all. Moss, however, one step ahead, has rented the connecting room on the other side, so by the time Chigurh removes the vent cover with a dime to grab the cash, it is already back on the road with Moss.
Tracking the satchel to a border town hotel, Chigurh's pursuit climaxes in a firefight with Moss that spills onto the streets, leaving both men wounded. Moss flees across the border, collapsing from his injuries and waking up in a Mexican hospital. There Carson Wells (Woody Harrelson), another hired operative, offers protection in return for the money.
After Chigurh cleans and stitches his own wounds with stolen supplies, he gets the drop on Wells back at his hotel and kills him just as Moss calls the room. Picking up the call and casually raising his feet to avoid the blood on the floor, Chigurh promises Moss that Carla Jean can be saved only by returning the money. Moss remains defiant.
Moss arranges to rendezvous with his wife at a motel in El Paso to give her the money and send her out of harm's way. She reluctantly tells Bell to try to save her husband, but Bell arrives too late. He sees a pickup carrying several men speeding away from the motel and finds Moss lying dead in his room. That night, Bell returns to the crime scene and finds the lock blown out in his suspect's familiar style. The scene shows Chigurh hiding behind the door of a motel room, observing the shifting light through an empty lock hole. His gun drawn, Bell enters Moss's room and notices that the vent cover has been removed with a dime and the vent is empty. In fact, we see that Chigurh was not present in the room when Bell entered, indicative of the aging sheriff's rising sense of anxiety and fear.
Bell visits his Uncle Ellis (Barry Corbin), an ex-lawman. Bell plans to retire because he feels "overmatched," but Ellis points out that the region has always been violent. For Ellis, thinking it is "all waiting on you, that's vanity."
Carla Jean returns from her mother's funeral to find Chigurh waiting. When she tells him she does not have the money, he recalls the pledge he made to her husband that could have spared her. The best he can offer is a coin toss for her life. She refuses to play, instead stating that the choice is his alone. Chigurh leaves the house alone and carefully checks the soles of his boots. As he drives away, he is injured in a car accident. He leaves before the police arrive.
Now retired, Bell shares two dreams with his wife (Tess Harper), both involving his deceased father. In the first dream he lost "some money" that his father had given him; in the second dream, he and his father were riding horses through a snowy mountain pass. His father, who was carrying fire in a horn, quietly passed by Bell with his head down and was "going on ahead, and fixin' to make a fire" in the surrounding dark and cold. When Bell got there, he knew his father would be waiting. Then he woke up.
