A woman in a plaid skirt and dark top dances in front of a large red building with ornate towers, then appears in a colorful, patterned indoor space, followed by a close-up of her face looking up at a moving train, then walking through a grand, arched subway station with blurred motion of other people, then standing in a dimly lit room with a wooden door, and finally sitting in a library with a large clock on a table between two lamps.
