Three people get lost in thick fog while driving along a mountain road. Husband and wife Leo and Anne and their friend Paul thus become participants in a drama which slowly gives vent to hidden emotions. The environment they find themselves in prompts questions of sexuality and the gradual disintegration of Anne and Leo’s marriage. The relationship between the three undergoes rapid development as the story unfolds, punctured by various unforeseeable twists. The psychological slant to the film is soon intensified with stylised sequences which unveil the main characters’ true motivations. Purely film media, including a divided screen and the use of numerous enlarged details, serve for the continual destruction of the initial unity of place, time and action. While the film retreats from the enclosing fog and the present, we follow Leo’s story back to the 17th century and, due to events long past, we begin step by step to follow the reasons why modern-day Leo refuses to become a father. The characters Anne and Paul also acquire different dimensions thanks to which they become more distant or, on the contrary, more intimate as the story moves towards its unexpected conclusion.
