Shi Shilun (played by Ouyang Zhenhua) had an accident when he was young. When he reappeared after three days of disappearance, he had forgotten all his experiences of the three days. He also broke his left hand and his thinking was not as flexible as before. His mother felt guilty about this and arranged everything for her son. When Shi Shilun came of age, she donated a county magistrate position to her son. With the help of his master, Shi Shilun served as an official with great success. Soon he took his mother and three wives to Jiangdu County to serve as a county magistrate. Once, Shi Shilun encountered an accident in the wilderness and fell into a coma. In his dream, there was a fairy pillow and an old man was fighting with Shi Shilun. This is not an ordinary dream. The dream is both real and illusory, and it can guide Shi Shilun in solving cases in real life... In Jiangdu, Shi Shilun also met Rong (played by Guo Keying). The two were a pair of enemies at first, but they fell in love with each other as they gradually got to know each other...
