Bob Lee Swagger (Mark Wahlberg), a sniper who has served in the US military for many years and has performed well on the battlefield, does not like to live with cold guns all day long. So, after retiring from the army, Swagger brought his beloved girlfriend and his loyal dog to the remote state of Arkansas. He began to live the peaceful life he had longed for. However, Swagger's happy and peaceful life did not last long and was ruthlessly broken. Swagger's former boss came to the door with a team of people. He hoped that with his many years of sniping experience, he could help the president when he gave a street speech and serve as a bodyguard for the president in the dark. Because the government had previously received news that terrorists or killers would take action, which would be detrimental to the president's personal safety. The kind and honest Swagger could not withstand the persuasion of his boss, so he agreed to accept the task. On the day of the President's speech, Swagger stood in the building opposite the podium and monitored. Suddenly, a gunshot rang out, and the President's personal bodyguard was shot and fell to the ground. When Swagger was about to pick up his gun to catch the gunman, a policeman suddenly broke in, pointed a gun at him, and asked Swagger to surrender. Swagger, who had not yet recovered, was confusedly wanted as a suspect in the assassination of the President. Fortunately, Swagger was agile and fell out of the window after being shot and fled the scene. After careful thinking, Swagger just woke up and realized that he had been framed as a scapegoat from the beginning. So Swagger desperately launched an investigation, chased the real murderer, and personally cleared himself of the crime. In a remote place in Arkansas, with a jungle, a cabin, a dog and his beloved girlfriend Sarah (Kate Mara), Bob Lee Swagger (Mark Wahlberg) with a beard lived a quiet life in seclusion. Until one day, a team of people came to the door. It turns out that Swanger was one of the best snipers. Because of a failed operation in Ethiopia, he was tired of the cold gun life and decided to retire to the mountains and disappear. The person who came to visit was Colonel Johnson (Danny Glover), Swanger's former boss. According to the intelligence agency's spy, terrorists are likely to take action during the president's next important street speech. The authorities can only hope to use Swanger's extraordinary sniper experience to ensure the president's personal safety in the dark. Unable to resist the plea of his former boss, Swanger agreed to accept this last mission. However, this mission is a dangerous trap! On the day of the president's speech, Swanger, who was lurking in the opposite building to monitor, not only failed to protect senior government officials, but was also shot in the back and fell off the window sill on the spot. Although he escaped by chance with his super ability, Swanger found that he had been confusedly wanted as a suspect in the assassination of the president! Framed as a scapegoat and forced to flee everywhere, Swanger, who was in trouble, decided to pick up the sniper again and start to fight back for revenge! Behind the scenes of the presidential conspiracy theory, Hollywood seems to smell the stench of money again. A series of conspiracy theory movies that were popular in the early 1990s were not lacking in quality. Among them, "JFK", a century-old conspiracy, has a structure that is difficult to distinguish between reality and fiction, which has stirred up a thousand waves, giving writers who are interested in this kind of inspiration. The best-selling novel "The Landing Point" published in 1993 is also the mainstay of this conspiracy wave. Although the popularity has changed many seasons, Hollywood, which has never forgotten nostalgia, has come up with the idea of adapting it, and the one produced by the way is "Sniper". According to the lack of gaps in modern hardcore action dramas, the trap-filled sniper revenge story is also quite exciting. The gimmick of the legendary sniper demonstrating the details of sniping on the screen, the action-oriented director's appearance, and the gray area of justice and revenge are all good entertainment for the public. Although the theme of being framed and fleeing may seem old-fashioned and aesthetically fatigued, the popular hunk Mark Wahlberg can push the old sports inspirational film "Invincible" to the box office champion, so such a commercial action thriller will surely not fall by accident. Highlights of the film How can a rifle change the world? Hunting in the pine forests on a snowy day, fighting in the bustling streets, these are just a small test for the retired sniper. Once his life is on the line and he may even die inexplicably, this top marksman will display his unique ability to enter and exit the heavily guarded White House as if nothing happened.
