The Vancouver Asahi baseball team consists of 2nd generation Japanese immigrants living in Canada. They play within a local amateur baseball league. The team got popular due to their fair play spirit, while struggling to fight against discrimination and poverty in their everyday lives.
Reggie (Satoshi Tsumabuki) is a 2nd generation Japanese immigrant who works at a sawmill in Vancouver. He is the leader of the team and plays shortstop. Roy (Kazuya Kamenashi) is the team's ace pitcher and works at a fishery field. Kaye (Ryo Katsuji) is the team's 2nd baseman and co-worker of Reggie. Tom (Yusuke Kamiji) is the catcher and works at a tofu shop. Frank (Sosuke Ikematsu) works at a hotel and plays baseball with the team.
Saburo, an ordinary high school student, travels back in time to the Sengoku era (1549). He encounters a young lord who looks exactly like him and is told, “Be my substitute. I’m the eldest son of the Oda family, Oda Nobunaga.” After the young lord leaves, Saburo is mistaken for Nobunaga by a vassal and taken to the castle. He starts to live as Oda Nobunaga from this day. The young samurai of the Oda family, which is merely a minor feudal lord, set out towards the extraordinary dream of unifying the whole country through the power of Saburo.
Saburo, a person from modern times who has no experience killing people, does not understand the willingness of the warlords of the Sengoku era to lay down their lives for their family. It is the same for the vassals too. They have had a hard time understanding Nobunaga’s actions ever since the ill-mannered, wilful Saburo took over. Despite this “generation gap across space and time”, they are soon on the brink of achieving their dream.
