A nun in a white mask holds a gun through a car window, then the scene cuts to a boy and a woman walking on a sidewalk, followed by a man in a black suit firing a gun from the roof of a black van, then a Boston Police car with flashing lights, then a close-up of a face submerged in water, and finally a soldier in a gas mask holding a gun in the rain. The setting shifts from a car interior to a city street, then to a street with a police car, and finally to a dark, rainy environment.
