Old Lin, a retired steel mill veteran with mobility issues, lives a materially comfortable yet emotionally desolate life. His routine is unexpectedly disrupted when he crosses paths with Ma Teng, an idle drifter brimming with "useless knowledge" and a chronic habit of abandoning projects midway, during a botched caregiver interview. What begins as a comedic clash of misunderstandings evolves into an extraordinary companionship. Through their unlikely journey bridging generational and social divides, the mismatched pair transforms from chaotic strangers into mutual pillars of support.
