In 2003, Yan Zhennan met Xiao Zhiheng for the first time. At that time, he was still a seven or eight-year-old child. He showed no timidity in the face of a group of people who bullied him. Instead, he attacked those people crazily like a wolf cub. I haven't seen such a wolfish child for a long time. Later, Yan Zhennan adopted Xiao Zhiheng and trained Xiao Zhiheng to be the first person to enter the police academy. Perdition or redemption? Can Xiao Zhiheng still defeat fate and take control of his life?
