A well-designed car accident caused Jiang Chen, a grassroots cadre, to lose his legs, and also allowed him to see through the ins and outs of the officialdom. Three years later, he returned to his official career in a wheelchair, starting as deputy director of the sub-district office. With his extraordinary political wisdom and deep concern for people's livelihood, he made his way step by step in the whirlpool of power. When everyone thought he was just a useless person, he used impossible tasks to send his opponents to the trial seat. Every case he investigated made the whole city tremble. This is not a simple history of promotion, but a story of how a man whose wings were broken grew his fangs again in the jungle of power.
