Picture three places. 1. A workshop in Germany where we follow the making of a prosthetic hand. 2. A traditional glove-making workshop in Millau, in the south of France. 3. A jeans factory in Istanbul, illustrating large-scale industrial production. A succession of three workplaces, but with a common viewpoint and subject: the relationship between the hand and the machine, the work and the material, all of them patiently and rigorously observed.
