[1] Three young girls, Jisook, Misun and Eunkyoung take a trip to the mountainous Kangwon Province of South Korea.

Jisook has just broken up with another married man, and she is lonely and unhappy with her current situation.

He is married, but Jisook returns another day to see him and they end up falling-over drunk again.

The second half the film then follows the situation of Sangwon, the married man that Jisook has just broken up with.

In a typically symmetrical fashion, after a repeat scene where it becomes apparent that both of them are on the same train, Sangwon also visits the Kangwon Province with a friend and the paths of the two characters cross without them ever meeting there, both of them encountering a couple involved in a murder investigation.
