40 years old Tachibana Yuzuki has just taken on a job as a mountain climbing guide. While on her first solo guide job to climb Mount Myoko and Mount Hiuchi, she meets the female members in her group: Yumi and Ritsuko who work in a departmental store and Mitsuko who works in a welfare facility. With various reasons and issues, these first-time climbers try to scale the mountains while led around by the nose by Kijima who is Yuzuki’s senior but younger than her. ~~ Adapted from the novel “Yamaonna Nikki” by Minato Kanae.
