In a convenience store, a person in a red shirt runs toward another person in dark clothing, who then runs toward a glass door and smashes through it, causing a bright flash. The scene cuts to a man in a camouflage shirt holding a rifle, aiming it forward in a dimly lit room. The sequence ends with a view of a cluttered kitchen, where a person is seen moving quickly, followed by a shot of the man in camouflage holding the rifle as he moves through a doorway.
