A weathered lighthouse keeper in a heavy navy wool sweater stands at the top of a spiral iron staircase, one hand on the brass railing, and speaks calmly to camera in a low, gravelly voice: "Forty years, and the light has never once gone out. Tonight won't be the first." Behind him the great Fresnel lens turns slowly, throwing a sweeping beam across rain-streaked glass. Locked-off medium shot, eye level, 35mm lens. Cold blue storm light from outside, warm amber glow from the lamp on his face. Sound: wind howling against the tower, rain hammering the windows, the low mechanical hum of the rotating lens, his voice clear and close. Natural film grain, no on-screen text, no music.
