Su Wenyuan searches desperately for his son for twenty-five years, finally reuniting with Su Heng at a breakfast shop. A bowl of hot porridge brings the long-separated father and son closer again. After learning that his son's little shop has repeatedly suffered bullying, Su Wenyuan stands by him to protect the fruits of years of hard work and help the wronged shopkeepers obtain justice. After the turmoil subsides, Su Heng does not rely on his father's identity. Instead, he starts with a loss-making store and earns people's trust through honest, diligent management, eventually taking on greater responsibilities. The lost years can never be recovered, but from this moment onward, father and son can make the days ahead warm and fulfilling.
