This drama describes an unconventional father-son relationship, a heartwarming, nostalgic, light-hearted, and humorous story. The father and son have always had a distant relationship; the son always thought his father's so-called principles were outdated, while the father often claimed he had extraordinary encounters in his youth, which the son believed were merely excuses for his failures. One day, after the father is involved in a car accident and falls into a coma at death's door, the son feels deep regret and loss. Unexpectedly, he time-travels back to his father's younger days in the 1960s, when life was simpler and full of human warmth in Yuen Long's Tang Family Walled Village. By chance, the father and son become good friends. In this simple and sincere era, the son relearns how to interact with people, experiences the value of close interpersonal relationships, and comes to understand his father's worldview. He also discovers that his father’s "extraordinary encounter" in his youth was actually meeting his own unborn self.
