"Behind the wall" is a documentary on Dimitris Papaioannou, a Greek director, choreographer, performer, visual artist, but it isn't a typical artist's portrait. By following the preparation of his most mysterious and essential work, called "Still Life", the film focuses on his vision and philosophy, his working method and routine, his dedicated collaborators. "Behind the wall" draws a parallel between the creative process and the myth of Sisyphus, pointing out that life and work of great artists are symbiotic.
