In an era rife with gun violence perpetrated by men, Shooter is the story of a shooter-massacre stopped before it can happen. When Jim sees a teenage boy with two shotguns beneath his trench coat nearing the entrance of the local high school, Jim pulls his own firearm and stops a potential massacre. Jim is a hero. But as more details about the incident are uncovered, what really happened becomes a lot less clear. Shooter is a human tale focusing on the fallout among three friends, each of whom may have contributed in some way to the would-be shooting.
