This is a completely new kind of SF film which shows the future of our civilization profoundly and quietly but humorously, having "The Box" as the leading role. It tells allegorically like a picture book the possibility of the peaceful co-existence of high technology and tree, a symbol of nature. The quite unique world of this film is depicted in its simple and beautiful images, which can entirely change our images for monochrome films. There is the future no one has ever imagined in "The Box".
