Video · made with Seedance 2.5

A cinematic short: a lighthouse keeper, a woman in her late 50s with silver-streaked dark hair in a low bun, navy wool peacoat over a cream knit sweater, climbs a narrow stone spiral staircase at dusk. Brass lantern light flickering on wet stone walls. Handheld 35mm, warm practical lighting, rain outside, gentle orchestral score.
