This is a spy impossible-style movie, but the protagonist is replaced by a sniper. Bob (Mark Wahlberg), the outstanding retired American sniper, was enjoying his leisure time after retirement in Arkansas. Unexpectedly, his former boss came to visit him, hoping that he would accept a new task-acting as an invisible sniper to secretly protect the president on the day of his street speech. Although he was extremely reluctant, he couldn't resist the lobbying of his boss and Bob finally agreed. On the day of the president's speech, Bob was carefully observing the situation around him when suddenly the venue was attacked by gunmen and the bishop of Ethiopia, who was next to the president, was killed. Bob was chased by the police as an assassin. Knowing that he had become a scapegoat, Bob tried his best to escape despite being shot twice in his body. Bob's only way out at this time is to find out the real murderer behind the scenes and clear his name.
