After the forced suicide of Nobunaga Oda at the Incident at Honno-ji, powerful figures Katsuie Shibata (Koji Yakusho), Hideyoshi Toyotomi (Yo Oizumi), Nagahide Niwa (Fumiyo Kohinata) and Tsuneoki Ikeda (Koichi Sato) all meet to decide on a successor. The meeting became known as the Kiyosu Conference and Japan's first group made political decision. The leaders there become torn between two successors. Meanwhile, Hideyoshi Toyotomi (Yo Oizumi) has plans to simultaneously woo the woman (Kyoka Suzuki) he loves and gain the throne himself through proxy.
