“Cruising”

In a classroom setting, a young woman with long dark hair raises both hands above her head with palms facing forward, then lowers them, repeating this motion in a loop. The scene cuts to a close-up of a different young woman with dark hair, who holds a white, cylindrical object in front of her face, partially obscuring it, while looking toward the camera. The background in the close-up is a white, sheer curtain.
