Natasha of the RainbowMovie

In 1932, the shadow of war threatens, but Japan is still at peace. A sponsor of the Imperial Symphony, Lord Kuretake Kimiya, is deathly ill. He calls to his bedside Sanjou Kaoru, who is both the fiancé of his daughter Umeko and an up-and-coming conductor. Lord Kuretake has a very serious request: Many years ago, he had a daughter with a Russian woman and he begs Sanjou to search for her in Shanghai. Because her mother, Anastasia, an opera singer, was a close friend of the princess, when the revolution came, she vanished with the imperial family. Since then, Kuretake has married and had a family, and he wants his daughter Natasha to be raised in his home.
