The subject of this film is the dream. You'll see a man in a fantastic place where men and women must find their own dream using a fixed bus where a false landscape painted on 2 revolving vertical rollers in front of the windshield ravels. This fantastic place is very white and with no hill where each person has its small space where it carries out its dream. You'll see even a man in a sand vat playing with the model of a ship of corsair. The hero seeks in vain but does not find until he meets a woman in the same case as him, in this bus. They find their dream together while falling in love because their dream was a dream of love. There is even a scene where they are seen intertwined, layed, cherishing themselves in white sheets... I also remember that this dream is disapproved because it enfraint a rule governing this place of the dream. Here, it is all which I remember.
