Sakura means cherry blossom in Japanese. In the room of a deceased person, police discover a few drops of old blood on a woman’s garment patterned with sakura. The murder victim holds a very special position: he was the president of a Japanese company. The investigation is inevitably affected by international relations and public opinion, and often goes astray. The young police officers on the case face confusion and trials amid unspoken workplace rules. After the real culprit is caught, the battle of human nature truly begins. Behind the case lie more than schemes, resentment, and romance. Even more shocking are the foreign boss’s psychological enslavement of others and the local executives’ groveling devotion, which drag their families into the mire as well. Once a person’s conscience is lost, there are no limits left. In the end, the one buried is the person who has fallen into depravity.
