Goodbye!!!

Two characters stand on a rooftop overlooking a city at sunset, then the scene cuts to a close-up of a man's face, followed by a shot of a woman in a harness standing on a rooftop with a man beside her, then a close-up of a hand holding a knife to the man's throat, and finally a wide shot of a man walking across a rooftop. The setting is a city enclosed by large walls under a cloudy sky.
