A current of thought unites the three episodes in a coherent way, embodied with few elements, and that makes of space, time, and movement, purely cinematographic modes of expression. Voice is not needed. Yes there are sounds, music, but not human voices, as in primitive cinema. There are faces, slow or fast movements, despair, fatality, a barely glimpsed horror, desire and fear of freedom. There is also love, perhaps as an illusion, rather than as a reality.
