Mitsunari Ishida was killed in the Battle of Sekigahara. Following the war, a meeting is held at Edo Castle to determine the fates of those that had stood against the Tokugawa clan. Yukimura Sanada's sentence, in particular, attracts heated debate from all those present. Amidst all the voices baying for his blood, not least Hidetada Tokugawa, who had fallen in battle to Yukimura, and was late in reaching Sekigahara as a result, Ieyasu Tokugawa asks Yukimura's brother, Nobuyuki, for his thoughts.

As the Tokugawa clan's messenger, Nobuyuki heads to Aizu to inform the Uesugi clan of their punishment following the battle of Sekigahara. He meets Kanetsugu Naoe, who refuses to accept the severe, and almost cruel, demands, but Nobuyuki refuses to budge too. On the other hand, while Yukimura escaped the death penalty, he was leading an empty life, without being able to find the "meaning of his life" that Nobuyuki had asked him to reconsider. But one night, things start to get noisy in his vicinity.

This is the beginning of what is now known as the Winter Siege of Osaka. The Tokugawa army tries to assert its numerical advantage, but Osaka Castle and the Sanada Maru fortification stand firm against them. Yukimura Sanda, Keiji Maeda, Kiyomasa Kato, and Masanori Fukushima fight hard as part of the Toyotomi clan's forces, refusing to give an inch to their enemies. With winter upon them, a cold wave saps both armies of their energy. That's when Yukimura has to face off with Kanetsugu Naoe, who he had shared a vow of righteousness with, as an enemy. Meanwhile, as Osaka Castle continues to get bombarded by artillery fire, Nobuyuki Sanada charges in alone in a bid to negotiate a truce.
