Bob Lee Swagger (Mark Wahlberg), a retired Gunnery Sergeant Marine Scout Sniper, is one of the few snipers in the world whose sharpshooting abilities allow him to “take out a target from a mile away.” He reluctantly leaves a self-imposed exile from his isolated mountain home at the request of Colonel Isaac Johnson (Danny Glover). Johnson appeals to his expertise and patriotism to help track down an assassin who plans on shooting the president from a great distance with a high powered rifle. Johnson gives him a list of three cities where the President is scheduled to visit so Swagger could determine if an attempt could be made at any of them.
Swagger assesses each of the locations and determines that a site in Philadelphia would be most conducive to a long range assassination attempt. He passes this information to Johnson, who purportedly arranges for a response. This turns out to be a set-up: while Swagger is working with Johnson’s agents â€” including a local police officer â€” to find the rumored assassin, the Ethiopian archbishop is instead assassinated while standing next to the president. Swagger is shot by the officer, but manages to escape. The agents tell the police and public that Swagger is the shooter, and stage a massive manhunt for the injured sniper. However, Swagger has a stroke of luck â€” he meets a rookie FBI special agent, Nick Memphis (Michael PeÃ±a), disarms him and steals his car.
Later appearing in a closed meeting with the Director of the FBI and the United States Attorney General present, Swagger clears his name by loading a rifle round (supplied by Memphis) into his rifle (which is there as evidence since it was supposedly used in the killing), aiming it at the Colonel and pulling the trigger â€” which fails to fire the round. Swagger explains that every time he leaves his house, he takes out all the firing pins replacing them with slightly shorter ones, thus rendering them unable to fire until he returns. Although Swagger is exonerated, Colonel Johnson takes advantage of a legal loophole â€” the Ethiopian genocide is outside American legal jurisdiction â€” and walks free. The attorney general approaches Swagger and states that as a law enforcement official, he must abide by the law (he insinuates that if it was the “wild west” it would be appropriate to clean the system with a gun). Afterwards, the Colonel and the Senator plan their next move while at the Senator’s vacation house â€” only to be interrupted by an attack by Swagger. He kills both conspirators, one of the Colonel’s aides and two bodyguards, then breaks open a gas valve before leaving. The fire in the fireplace ignites the gas, blowing up the house. The final scene shows Swagger getting into a car with Fenn and driving away.
