The video appears to show an outdoor scene with a rocky, mountainous backdrop. A crowd of people of varying ages is seated on a rocky slope, facing the camera. In the foreground, a man is lying prone on the ground, aiming a rifle. There are other rifles propped up beside him. A rectangular black case lies beneath him. The man fires the rifle, and the camera remains steady throughout the sequence. The crowd seems to be observing the action.
