A blonde woman with a serious expression looks off-screen, then turns her head slightly to the side, her face remaining in profile. The scene cuts to a woman with dark hair in a black leather jacket standing on a city street at night, looking forward with a tense expression. The scene cuts again to a blonde woman sitting in a dimly lit room, looking up and to the side with a slight smile. The final scene shows a woman with dark hair hunched over, hugging her knees to her chest while sitting on the floor.
