The story of the film is based on the classical tale about seven naughty sons, whom their mother cursed in anger and thus turned into ravens. When their youngest sister grew up, she decides to find her brothers and to free them. However, she falls in love with a young Prince.
The fairy tale tells the story of a very wise Japanese judge, Ooka, who, when judging disputes between merchants, slaves, and even mayors, always listens to both sides first and then makes a fair decision. With his tricks and correctly asked questions, no perjurer or swindler escapes his notice.
