A close-up of a human eye with a greenish-blue iris shows the pupil constricting and dilating repeatedly, with the eyelid briefly closing and reopening, set against the surrounding skin. The scene then cuts to a man and a woman walking away from the camera down a sun-dappled garden path lined with lush greenery. The view shifts to a field of tall grass swaying in the wind, followed by a shot of a graffiti-covered wall beside train tracks, seen from a moving vehicle.
