The film is about a village postman and his delicate relations with his son.
The village postman delivers letters and newspapers in the mountain area by foot. Day after day, year after year, he comes and goes, comes and goes... Although the work is monotonous, the postman never complains. In his eyes, the tedious work proves his worthiness to the society.
The postman's son, although eager to leave the mountain home, fails to pass the college examination. With little choice, he comes back to his father. At this time, the postman grows older and weaker. Feeling that he can no longer handle the daily delivery, the postman asks his son to take over his role. From that day on, the son begins to deliver letters and newspapers door to door in the mountain region.
On the first day the son takes the position, his father insists to escort him. From one village to another, the two do the job together but seldom talk to each other. There seems to have a thin wall that separates them. In a small village, the son sees a beautiful girl, but has to leave under his father's pressure. Gradually, the father starts to understand his son, and regrets what he did to his wife for decades.
On the muddy and narrow road of mountain villages, father and son break the silence at last...
