Bang

A young girl in a green dress stands with a dog on a leash and a man, smiling and raising her arm, before her face is shown in close-up with a dark splatter on her cheek, which then transitions to a scene of a woman in a school uniform looking shocked, with the girl's eyes and the splatter overlaid, followed by a shot of the girl's face with a bloody mouth and the splatter still on her cheek, and finally a view of a room with a bloodstain on the floor, all set against a backdrop of a house with a blue door.
