A man in a dimly lit room looks down with a pained expression, then the scene cuts to a bloodied man lying on a gurney with an oxygen mask, followed by a woman in a dark tank top holding a weapon in a shadowy environment, then a woman's face in close-up showing a scream, then a figure in dark clothing moving through a dark hallway, and finally a man's profile in a bathroom as he leans forward. The sequence takes place in a series of dark, tense indoor settings including a room, a medical or laboratory area, a dark outdoor or enclosed space, and a bathroom.
