Schmitke (2014) on Netflix

Julius Schmitke is a fifty-seven-year-old German wind turbine engineer. He feels ill and his body creaks, crunches and groans with age. One day, he is sent somewhere to the Czech side of the Ore Mountains to fix one of his old model, a C 174 turbine that, mysteriously, will not stop creaking and squeaking, just like his own body does. But this is not the only mystery that awaits him. His colleague disappears, strange things happen, and Schmitke starts to "feel" the spirit of the forest around him. The longer Julius wanders around the harsh and misty mountains, the more it surprises him that this entire expedition into the ominous and unknown jungle seems to be a return to old, familiar places within himself.
