Retired general Wang Jianjun ended his ten-year military career and returned to his hometown with concern for his family, only to find that evil forces were rampant and the people had been oppressed for a long time. In the face of threats and frame-ups, he always adhered to his military beliefs, bravely protected his family, and worked with the forces of justice to investigate criminal evidence and uncover layers of "protective umbrellas." In the process of protecting the rights and interests of retired veterans, poor students and ordinary people, he defended fairness and justice with responsibility, courage and responsibility, allowing the sunshine to shine in his hometown again.
