Keisuke Asai (Toma Ikuta) and Ryu Ji-yong (Yang Ik-june) are old college friends on an annual pilgrimage to the mountain where their hiking buddy, Sayuri (the single-named Nao), disappeared 16 years earlier. When they get caught in a snowstorm and Ji-yong sustains a serious leg injury, he makes what he presumes will be a deathbed confession, admitting that he murdered the woman they’ve been mourning for all these years.
