Shooter (2007)

Synopsis
A top Marine sniper who previously abandoned the military after a routine mission gave way to tragedy is double-crossed by the government after reluctantly being pressured back into service in Training Day director Antoine Fuqua's adaptation of Stephen Hunter's novel Point of Impact. There was a time when Bob Lee Swagger (Mark Wahlberg) was the best trigger-man in the military, but after growing disillusioned with the system, he disappeared without a trace. After being located at his remote mountain retreat by high-profile government officials following an extensive search, Swagger is coerced back into service in order to stop a determined assassin from taking out the President of the United States. In the process of carrying out his mission, however, Swagger suddenly realizes that he has been betrayed when he becomes the subject of a nationwide manhunt. Now wounded and desperate to reveal the culprits behind the conspiracy before it's too late, Swagger sets into motion a revenge plan that will send shockwaves rippling to some of the most powerful and corrupt leaders in the free world. Danny Glover, Rhona Mitra, and Ned Beatty co-star in this conspiracy-driven action thriller that asks what it truly means to serve one's country. ~ Jason Buchanan, All Movie Guide
