A night in the life of Isaac, a jewish Russian man who survived the nazi holocaust, and Sophie, a catholic Polish woman. They are both refugees. Since thirty years they live in a garret in London, where Isaac has created a sort of maze of doors on which he has engraved and painted the symbols of their past. In this space, trapped in the history and yet in a time-free dimension, the two characters fight, take care of each other and make love, linked by mutual need.
