Synopsis：In the early 1990s, top police academy graduate Du Xiangdong was unexpectedly assigned to a detention center instead of his desired post. Under his watch, two detainees managed to escape—one was later found dead, while the other disappeared without a trace. The fugitive, Xu Wenguo, remained on the run for years, while prison officer Du Xiangdong relentlessly pursued him. However, the case progressed slowly. As time passed, this pursuit seeped into the lives of their families and friends, becoming the driving force and backdrop of both men’s fates. Over more than 20 years of tactical battles and psychological warfare, their struggle reflected the endurance and brilliance of ordinary people caught in the tides of history.
