I’m back.

A man in a white coat stands in a dark, industrial setting illuminated by red and green lights, then the scene cuts to a chaotic fight where multiple characters exchange gunfire in a dimly lit room, followed by a man in a long coat firing a weapon in a warehouse-like space, and finally a close-up of a man's face as a blade flies toward him, ending with a man in a dark jacket firing a machine gun in a room with red banners on the wall.
