A Japanese man wakes up alone in a brightly illuminated white room with no windows or doors. When he presses a mysteriously phallic protuberance that appears on one wall, a pink toothbrush materializes from nowhere, clattering to the floor and setting in motion a genuinely bizarre chain of events. Soon the imprisoned man is engaged in absurd and hilarious attempts to escape the gleaming room. (imdb)
