This is a story of lost love, a common theme for Korean movies and TV dramas. Most of the story is told in a series of flashbacks from the alternating perspectives of the two main characters. One is a mountaineer with a day job that just isn't as fulfilling as climbing mountains, which is his true love. The other is a college student who plays baseball and hates the idea of climbing mountains. They both find themselves on a mountain together though.
The 'present day' events of the story take place on Asiaq mountain in Alaska, where two men share stories of the women that changed their lives, not knowing how closely connected they actually are. During the climb, difficulties arise and they're forced to wait out a storm together in a cave, where they get to know each other. They're both there on the mountain for different reasons, but at the same time they're both there to reconnect with a part of their lives they'd lost.
