I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Saigo no Yakusoku Movie plot: Janitors Satoru Mashiko (Satoshi Ohno) and Haruo Iio (Kazuki Kosakai) are driving towards Energy Bio Corporation for work when motorcycle courier Nozomu Goto (Jun Matsumoto) passes by them. Goto goes to deliver a package to Yuriko Niimi (Meisa Kuroki), the daughter of the president of Energy Bio Corporation. Meanwhile, Fuyuko Todoroki (Nene Otsuka) orders a cappuccino from coffee shop employee Akira Tanada (Masaki Aiba). They talk before she has to leave to meet with insurance salesman Yukio Tomizawa (Sho Sakurai) downstairs. As Mashiko and Iio start cleaning, Tanada apologizes for giving security center employee Shuji Yamagiwa (Kazunari Ninomiya) and new security manager Shinichiro Okanaka (Naohito Fujiki) the wrong order. At 3:00p.m., a disguised man with a rifle informs everyone that he and his allies have hijacked the building and set up a bomb that will go off in ninety minutes should President Niimi (Masahiko Tsugawa) not arrive with the ransom. Before she is locked in with Tomizawa, Fuyuko and the rest of the hostages in the fifth floor lobby, Yuriko runs off with Goto running after her. At the police station, Niimi and chief detective Genji Morozumi (Yukiya Kitamura) keep in contact with a hiding Tanada. Meanwhile, Yuriko quickly collects company data worth more than the ransom money. She reveals how she believes her father will only come to save his company. In turn, Goto reveals his own past of how his trusted friend died ten years ago. They cut off the power, which allows most of the hostages to escape the lobby. Okanaka distracts the hijackers to give Yamagiwa the chance to open the B-1 doors on the second floor for the hostages to escape the building after the power returns. Tanada informs the police that the basement doors are open, and Mashiko chooses not escape with Iio. After the escaped hostages manage to get outside, Goto tells Yuriko to go while he tries to take down the hijacker chasing after them. The doors close in front of Yuriko, who stops when she hears a gunshot and sees... My question: What did Nimi initially refuse to admit he distributed?
