An unidentified body. A hard-boiled cop with a rookie partner. A trail of clues that seem to go nowhere - until they lead straight to the top. In other words, a classic detective story, but hardly a genre-bound bore. As a pioneer of Japanese noir, Shochiku veteran Nomura takes these crime-story conventions on a wild ride in The Castle of Sand, making the story of detectives Imanishi and Yoshimura (and one mysterious dead cop) more than the sum of its parts. The innovative thriller is considered to be one of Nomura's best, and won the jury prize in the 1975 Moscow Film Festival.
