Paul Robaix, a famous director, wants to film the Puccini opera on location in Japan under the title Madame Butterfly, with the dialogue spoken in English and the score sung in Italian. His wife, Lucy Dell, has been the leading lady in all of his greatest films, and she is more famous. He feels that she overshadows him and he would like to achieve success independent of her. By choosing to film Madam Butterfly, he can select a different leading lady without hurting her feelings, because she, as a blue-eyed, red-headed comedy actress, would not be suitable to play a Japanese woman in a tragedy. As a surprise, she visits him in Japan while he's searching for a leading lady. To surprise him further, she disguises herself as a geisha at a dinner party, planning to unveil her identity during the meal.
But she is delighted to discover that everyone at the dinner party, including her husband, believes her to be a Japanese woman. When she learns that the studio has decided to only give her husband enough funds to film the movie in black and white because there are no big stars in the film, she decides that she will audition for the role of Butterfly, without telling her husband, but that the studio will know and therefore give him the budget he needs to make the film he wants.
She gets the part and is wonderful. Through the course of the film, Lucy Dell begins to become concerned that Yoko will steal her husband's affections, though he never does develop feelings for the invented character.
When viewing the film's negatives, with the colors reversed, he figures out her duplicity and, thinking she is doing it to steal credit from him so that once again he will not get the artistic praise he deserves, he becomes furious. To retaliate, he decides to proposition Yoko. Greatly distressed, she flees. Paul then entertains the idea of divorce for what he sees as him being betrayed by his wife.
Their "reunion" before the premiere is cold, Paul believing she will expose her identity there for betraying him, and Lucy believing that Paul was trying to sleep with Yoko. Her original plan was, at the end of the premiere, to reveal Yoko's true identity, which will astound Hollywood and practically guarantee her an Academy Award. Instead, her then trusted friend, Kazumi, gives her a present of a fan that was owned by a very popular geisha. The fan was inscribed with the saying: "No one before you, my husband, not even I." So, she takes off her geisha makeup, appears as herself, tells everyone that Yoko went into a convent and will no longer be performing, and keeps her identity secret. She and her husband reconcile when he informs Lucy that he knew she was Yoko.[5]
