-F 'prompt=At dawn, a low tracking shot glides along a misty mountain lake, the water still and silver-blue. An old fisherman in a weathered wool sweater rows a wooden boat into frame, each oar stroke leaving slow rings across the surface. The first sunlight breaks over the ridge behind him, turning the mist gold and catching the grey stubble on his face. He rests the oars, closes his eyes and breathes in the cold air. The camera drifts closer as he begins to hum a low folk melody. Water drips from the oars, a loon calls across the lake, and his humming echoes softly off the hills.' \
