A series of scenes shot in the Paris metro, edited to the rhythm of the trains’ automatic doors. The kaleidoscopic effect of viewing through the windows of trains as they pass each other determines the geometry of the image. A composition of parallel and divergent vertical and horizontal movements: those of the camera but also of the trains and the scrolling publicity panels. The film moves in the interstices of time and space, addressing the tensions between static and dynamic, present and absent, fiction and reality.
