The plot might seem banal, but what is fascinating in this film is the atmosphere: mainly, mysteries that remain unsolved: what is the shady affair in which the woman is involved, and what is her role? Is or isn't the man a marquis? Who is the young man played by Fabrizio Bentivoglio, and why does he own that car? Does Basque nationalism have to do anything with the story? Everybody has something to hide, everybody seems guilty. The jazzy sound track of the movie (Cole Porter, John Coltrane) adds to the nostalgic tone, as well as the voice-off reporting the protagonist's existential, regretful reflections.
