CASTLE OF SAND is an engrossing, laid-back police procedural that captures your attention even when the plot seems fairly ordinary. A Tokyo cop (Tetsuro Tamba) is troubled when a retired cop is found brutally murdered, with no evidence save the vague recollections of a few townsfolk. At times, the story is reminiscent of a regional travelogue, but in learning more about Japan, Tamba hones in on a small set of likely suspects, but everyone is so agreeable that uncovering the truth becomes like rooting out the one hidden evidence of violence in a sea of potential data.
Regrettably, the film unravels in the final forty or so minutes, when the remainder of the story is told with musical accompaniment of a famous pianist. The plot becomes frankly loses credibility and even becomes rather nonsensical. The movie changes mood and style, and dripping with melodrama.
