A poetic documentary story, mainly using pictures with scarcely any colours (which are the more effective in the otherwise gloomy surroundings), tells of a felt factory for valenki. The whole technical process – from the “bathing” of the wool fibres in water, to the cutting of the boot shape from the prepared material – is depicted in the form of a trance-like visual sequence, accompanied by the sound of working machines. The close-ups of the workers are like counterpoint. Everything around them is steaming with heat. The valenki factory in Smilovichi in Belarus has been operating since 1929.
