A young boy in a red and gray striped shirt rides a red tricycle down a suburban street, viewed from behind, then the scene cuts to a close-up of the tricycle's wheel spinning, followed by a shot of the boy from the side wearing an American flag mask. The sequence alternates with three men in suits and gas masks, each holding a different weapon—a baseball bat, a crossbow, and a submachine gun—against a dark background.
