Gun

A man in a black jacket and fingerless gloves adjusts his clothing while standing next to a car in a parking lot, then the scene cuts to a man in a black cap looking down, followed by a man in sunglasses walking away from a car, then a man holding a rifle in a school hallway with papers on the floor, then a close-up of a man with two cigars in his mouth, and finally a blurry image of a room with objects falling.
