Lu Jingchuan is a gifted watchmaker who has worked tirelessly for three years at Hengchang Watch Shop, owned by his second uncle, turning a struggling business into one that earns a net profit of one million yuan. However, the promised 30% share of the profits amounts to just 30,000 yuan. Furious, he walks away and opens his own shop in a small alley, staying true to his principles: restoring old watches to their original condition and never deceiving customers. His honesty and skill earn him the trust of neighborhood residents and longtime customers. Meanwhile, his second uncle and cousin resort to every unscrupulous trick to make quick money: passing off new movements as original parts, falsifying repair records, and using so-called old-for-new exchanges to undervalue and resell customers' watches. When their lies are exposed, Hengchang is shut down and investigated. With his craftsmanship and integrity, Lu Jingchuan embarks on a fresh chapter in both his career and love life.
