Yun Gi-jun (Shin Seong-il) has become the executive director of a pharmaceutical company by marrying the widowed daughter of the company CEO. With the general shareholders' meeting coming up shortly, his wife suggests that he visit his hometown of Mujin and he takes her advice. In Mujin, Gi-jun, who is draft dodger and a one-time tuberculosis patient, meets a music teacher named Ha In-suk (Yoon Jung-hee). He falls in love with In-suk, who, just like he did as a young man, wants to leave Mujin and move to Seoul. However, he receives a telegram from his wife telling him to return to Seoul immediately as he has been promoted. Gi-jun sets off from Mujin without leaving one word of explanation to In-suk.
