Assistant Inspector Takeuchi Koji, who had failed to protect the prime minister as a security police, retired from the front line. One day, he is suddenly ordered by the Diet lawmaker Ishinabe Kiriko whom he had guarded while cracking a bizarre murder case, to protect the famous young violinist, Washio Hanako. Hanako took lessons in Europe from a young age, and won awards at numerous international competitions that catapulted her to fame. On this occasion, she has triumphantly returned to Japan for a concert tour around the country. At the same time, Hanako has also been supportive of the democratisation of countries under military dictatorships. It appears that her life is being targetted by a country’s military rulers because of the political statements she reiterates. Hanako is always accompanied by her mother Sayoko who works as her manager, and Takeuchi finds himself at the mercy of women once again. In the midst of this, a bomb is planted at a concert venue and eventually Hanako’s step-father Otani who was Sayoko’s ex-husband, is murdered. Is this a warning from that dictatorship to Hanako? The case goes international, but the detective in charge of Otani’s murder seems to think that the culprit is someone close at hand.
