Henry Brogan, a 51-year-old former Force Recon Marine Scout Sniper working as an operative of the Defense Clandestine Service of the Defense Intelligence Agency, is sent to assassinate a bioterrorist aboard a train in Belgium. Henry's spotter warns him of a young girl approaching the target, causing him to delay his shot until the last second, shooting the man in the neck despite aiming for his head. Disillusioned with killing, Henry retires.
In Buttermilk Sound, Georgia, Henry meets boat rental manager Danny and reconnects with his old friend Jack, who tells Henry that his informant Yuri claims that the target on the train was innocent. Demanding proof, Henry has Jack arrange a meeting with him. In retaliation, agency director Lassiter plans to kill Henry; Clay Verris, director of a rogue private military company codenamed "GEMINI", is denied permission to eliminate him.
Deducing that Danny is a fellow agent sent to monitor him, Henry befriends her. After his home is broken into by government agents, he calls his spotter, who is killed along with Jack and his mistress. Henry warns Danny, and they kill the assassins sent after them, realizing the agency wants them both dead. They escape to Colombia with Baron, Henry's former colleague, hiding at his home and planning to meet with Yuri.
Clay dispatches his top assassin to kill Henry. Fighting him off, Henry realizes the assassin bears an uncanny resemblance to himself as a young man. Arriving at a safe house, the assassin is revealed to be Clay's adopted "son" Junior. Curious about his similarities to Henry, Junior is ordered to finish the job. Danny suggests the assassin might be Henry's child, despite his denials.
Desperate for answers, Henry has Baron obtain a Gulfstream and transport them to Hungary. Testing DNA recovered from Junior, Danny discovers that his and Henry's DNA are identical – Junior is Henry's clone. Henry meets Yuri and learns of GEMINI's cloning project; the man he killed on the train was a scientist who tried to leave the project, having designed a method to produce clones devoid of pain or emotion. Henry calls Lassiter, who agrees to send Junior to bring Danny safely back to the United States.
Collecting Danny, Junior sets up a trap for Henry, who is warned via a covert listening device hidden in Danny's mouth. Ambushing the younger assassin, Henry explains to Junior that he is a clone, revealing their similar traits that no one else could know. Escaping to GEMINI, a heartbroken Junior confronts Clay, who insists he must defeat Henry in order to surpass him. Finding Henry, Junior allies with him to bring down Clay, and Henry urges Junior to quit in order to become someone better.
Baron is killed in an ambush ordered by Clay, with Junior knocking Clay unconscious after a brief hand-to-hand fight. After defeating a wave of GEMINI operatives, Henry, Danny, and Junior face another seemingly unstoppable operative with special body armor that is resistant to bullets, fire, explosions, and blunt trauma. They manage to mortally wound him, and he is discovered to be another youthful clone of Henry, lacking all emotion and ability to feel pain.
Defeated, Clay tries to justify his actions to Junior: clones with Henry's skills would spare the lives of soldiers while making operations incredibly successful. Disgusted, Junior prepares to shoot Clay, but Henry persuades him otherwise and does it himself.
Assured that no more clones were produced and they are finally free, Henry later meets with Junior, who has enrolled in college under the assumed identity of "Jackson Brogan" after Henry's mother's surname. Together, Henry and Danny plan Jackson's future.
