Three little chimney-sweepers fall down at the door of a farmhouse exhausted with fatigue and cold when the snow is falling. The most courageous of them knocks at the door to ask for help but the farmer sends them away and goes into the house quickly to sit down by the fire. Whilst these unfortunate creatures are lying almost lifeless in the snow, an angel appears in the sky who, with a gesture, transforms the scene, having the children and the bad rich man switching places.
