At night, two people are on the roof of a building

At night, two people are on the roof of a building. One is a woman in a dress, and the other is a man. The woman has a small object in her hand and is pointing it at the man, who is facing away from the camera. There is a clear barrier at the edge of the roof. The building is dark except for lights illuminating the roof, and there are trees in the foreground.
