Chen Jingdong, a 40-year-old architect of P9, a large Internet company, suffered from unemployment due to industry optimization, mortgage calls, and job search obstacles, and fell into a middle-aged desperate situation. A late-night encounter saw him witness the plight of DBL players, a grassroots basketball league, with no salaries and the league on the verge of disbandment. The dusty basketball complex collided with the IT people's data thinking, giving birth to an operational breakthrough plan. From then on, I split the thorns in an unfamiliar territory. This is not only a counterattack to save an endangered league, but also a passionate journey for a middle-aged man to protect his family, make up for the regrets of his youth, and redefine his self-worth.
