Is anyone there?

A person's hands are clasped together in a dimly lit room, followed by a woman with dark hair and a somber expression walking down a hallway, then standing in a dark, outdoor area with a man partially visible, then a person seen from behind looking through a glass door, then a wide shot of a person walking through a dimly lit, multi-level institutional space with rows of doors, and finally a close-up of a woman sleeping on a pillow. The setting transitions between an indoor room, a hallway, an outdoor area, a glass-walled room, a large institutional hall, and a sleeping area.
