In preparation for a feature-length film about windmills, an assistant director travels through the Vaud region to search for locations with windmills. The research leads to a serious engagement with the meaning and purpose of windmills, which has something Don Quixote-like about it in the age of nuclear power stations. The transitions between document and fiction flow constantly and result in a charming and intellectual mixture of seriousness and fun, determination and coincidence, weightlessness and the weight of meaning.
