The film centers on the reconciliation between a father and his son. Ah Lang, a youth from a small town, believes his father Ah Zheng never truly understands his occupation and the life he leads. In a pivotal moment, the story pivots from their strained dynamic into something surreal: Xu Tailang, a racer, wins the 2022 China Rally Championship while his aging father, Xu Zhengtai, watches with a smile that hides years of unspoken stories. What follows is a startling turn of events that blurs time and memory.

During a high-speed drive meant to celebrate, an oncoming train crashes into the rear of their car as it barrels along the tracks. The moment of impact doesn’t end the day; it launches Xu Tailang into a vivid, almost cinematic journey back to 1998, in the very town where he was born. The hospital gurney that once carried him toward the future becomes his doorway to the past, and he finds himself living a life he only knew through legends and rumors.

What unfolds is a blend of humor and heart as he navigates comical adventures with his younger father and a cast of characters who populate that era. He also meets his mother, Xiao Hua, a woman whose presence he never knew in life because of the tragedy that followed childbirth. Xiao Hua, portrayed by Xiao Hua in the cast, becomes a central figure in understanding the sacrifices that shaped Xu Zhengtai’s choices and the rhythms of the family he would one day return to.

As Xu Tailang observes life in 1998, he begins to piece together the man his father was long before becoming the older generation he now knows. He discovers the ways his father lived, the deep love he felt for his mother, and the circumstances that led to a prison sentence of six years. These revelations illuminate the sacrifices, missteps, and strengths that defined his father’s past, offering Xu Tailang a new lens through which to view him.

The journey through time deepens the bond between father and son, transforming unresolved tensions into understanding and respect. Xu Tailang’s odyssey becomes not only a voyage through a pivotal decade but also a quiet reconstruction of a family’s history. By the end, the father and son find common ground in the memories, regrets, and genuine affection that time could not erase. This awakening fosters a renewed sense of connection, suggesting that reconciliation might be possible even after years of distance and silence.

In a modest town where the rhythm of daily life is measured by the hum of engines and the quiet expectations of family, a young racer named Xu Tailand returns home after a championship win, hoping to bridge the gap that has grown between him and his father. The older man, Xu Zhengtai, watches his son’s triumph with a smile that hints at unspoken histories, while a lingering distance lingers in their conversations. Their strained dynamic, built on misunderstandings about ambition, sacrifice, and the weight of legacy, sets the stage for a quest that is as much about memory as it is about the road ahead.

The film’s tone walks a delicate line between surreal wonder and heartfelt comedy, inviting the audience into a world where a single, sudden collision on a high‑speed drive becomes a portal to another era. This unexpected twist does not so much thrust the characters into danger as it opens a doorway to the past, allowing the son to step into the very streets and moments that shaped his father’s younger years. The atmosphere is tinged with nostalgic warmth, punctuated by moments of whimsical humor that soften the deeper emotional currents.

Xu Tailand is a figure caught between modern achievement and the yearning for familial connection, his confidence on the track contrasting with his uncertainty at home. Across from him, Xu Zhengtai carries the quiet dignity of a man whose own story is veiled in quiet sacrifice, his past hinted at through fleeting glances and the stories whispered by those around him. The elusive presence of Xiao Hua, the mother whose life overflows with untold compassion, adds another layer of intrigue, offering clues to the forces that shaped the family’s history.

As the narrative unfolds, the film gently guides the audience through a blend of humor, nostalgia, and introspection, inviting viewers to ponder how the threads of yesterday can illuminate the relationships of today, and how a single journey through memory might rewrite the bond between father and son.
