What the fuck?

A man in a black leather jacket stands in a dimly lit, smoky club with red neon lights, then turns to face forward with a serious expression. The scene cuts to a man in a suit smiling and waving while holding a drink, then to the same man in the leather jacket aiming a large gun forward in a dark, industrial setting. The sequence ends with a woman dancing energetically in a crowded, brightly lit dance hall.
