In the early 1990s, Du Xiangdong, who harbored dreams of becoming a criminal police officer but was stuck in a detention center, unexpectedly noticed the extraordinary knowledge and manufacturing skills of the inmates Xu Wenguo and Yao Binbin, and admired them greatly. However, as the investigation deepened, the case of the two secretly developing firearms and being implicated in the murder of the workshop director Li Chao at the Six Machine Factory came to light. Du Xiangdong's former classmate, the criminal police officer Zhang Xiangyang, had a completely different judgment about the truth, prompting Du Xiangdong to embark on a solitary path to solve the case. Unexpectedly, during the transport of the two prisoners, an event occurred that allowed them to escape, and Du Xiangdong made every effort to apprehend Yao Binbin, while Xu Wenguo vanished into the vast sea of people. From then on, Du Xiangdong embarked on a chase for Xu Wenguo that lasted over twenty years. This pursuit not only infiltrated the lives of their family and friends but also became the driving force and backdrop of their fates. Amidst the currents of the times, it wrote out the brilliant glow hidden in the resilience of ordinary people, composing an epic of life for those tenacious souls rooted in the soil yet gazing at the stars.
