An unhappy young woman from an abusive family is married off to a fearsome and chilly army commander. But the two learn more about each other, love may have a chance.

Oda Nobunaga and Nohime were originally married to mend a hostile relationship between neighbouring regions. Unfortunately, they were like oil and water, making for a somewhat unhappy marriage. When Oda’s enemy, Imagawa Yoshimoto, attacks Owari with his vast army, Oda is devastated by the overwhelming gap in military strength. However, Nohime encourages him not to despair and the pair draw up a tactical plan that will allow them to overcome the odds.

The film stars Oguri Shun as an experienced mountain climber and rescue team volunteer named Shimazaki Sanpo. Sanpo loves the mountains and wants as many people as possible to experience everything they have to offer—so much so that he never holds a grudge against anyone for causing an accident due to their own negligence. Even if a fellow rescuer dies, he’s the kind of man who can look toward the corpse and say “You did your best.” One spring, newcomer Shiina Kumi (Nagasawa Masami) is assigned to the Nagano prefecture mountain rescue team where she experiences growth thanks to Sanpo’s guidance and the seemingly harsh training methods of the team’s captain, Noda (Sasaki Kuranosuke). However, she becomes depressed when she’s unable to translate her skills to a real-life situation. As her confidence wanes, multiple accidents occur simultaneously due to a mountain blizzard, forcing the entire team into action.
