In order to protect his younger brother, Lin Zhao, who was in decline, entered the palace of the capital and became a low-status son-in-law. Faced with the difficulties from the upper and lower levels of the palace, the jealousy of his sickly sister, and the frame-up of his green tea cousin, he relied on his extraordinary wit to pretend to be a pig and eat the tiger, and gradually exposed the hidden conspiracy of the palace. At the same time, he discovered the mysterious identity of his legitimate daughter Su Muwan. The two worked together to resolve the crisis, and eventually became the leader of the palace and defeated all the villains.
