This is a Mission Impossible movie, but the protagonist is a sniper. Bob (Mark Wahlberg), an excellent retired American sniper, is enjoying his leisure time after retirement in Arkansas. Unexpectedly, his former boss comes to visit him and hopes that he can accept a new task-to act as an invisible sniper to secretly protect the president on the day of the president's street speech. Although he was extremely reluctant, he couldn't resist the lobbying of his boss and finally agreed. On the day of the president's speech, when Bob was carefully observing the surrounding situation, the venue was suddenly attacked by gunmen and the Ethiopian bishop beside the president was killed. Bob was chased by the police as an assassin. Knowing that he had become a scapegoat, Bob struggled to escape after being shot twice. Bob's only way out at this time is to find out the real murderer behind the scenes and clear his name.
