A silhouetted figure walks forward against a red, stormy sky with a bright horizontal light, then the scene cuts to a soldier in camouflage and helmet crouching in a grassy field holding a weapon, followed by a man in a dark jacket standing with his back to the camera watching a large fire on a beach at dusk, then a close-up of intense flames and smoke, then two military jets flying in formation leaving white contrails in a cloudy sky, and finally the screen cuts to black.
