Border general Gu Changfeng was ordered to marry Su Jinshu, the frail merchant's daughter. After the marriage, Gu Changfeng discovered that this lady was pitiful when she was "sick", but she was very strange after she "recovered". She was especially good at performing shadow puppets. She used shadow puppets and mechanism skills to stir up chaos in the mansion and even the military camp. She didn't really come here to get married, but actually to investigate the truth behind the disappearance of her caravan on the ancient battlefield. One of the two is a god in military skills but straightforward in emotions, the other is proficient in all kinds of dramas and good at observing people's hearts but pretends to be a little white flower. They went from being a "contract couple" who disliked each other, to teaming up to solve the "ghost" mystery of the ancient battlefield through gags, and uncovered border smuggling and old cases. In the end, the general learned to "read the script", and the actress also showed her sincerity, and they became the most exciting rivalry in each other's lives.
