At the end of the Qing Dynasty, Tianjin Wei. In order to raise money for his master's medical treatment, Chen Shou, an apprentice in the funeral procession, took on a strange job - to "paint the skin" on the body of a young lady who was disfigured in a fire from the Liu family of a local wealthy gentry, so that she could honorably complete an underworld marriage. The reward was a thousand taels of silver, but the price was to live in the legendary Liu family mansion that was "only accessible but not accessible". As the skin painting work progressed, Chen Shou discovered that this "corpse" was full of weirdness, and there seemed to be a warm undercurrent under the cold skin. And in that so-called ghost marriage, the groom turned out to be a paper man. He gradually understood that what he was participating in was not a wedding, but a horrific soul-changing ceremony, and the paintbrush in his hand was the last tool to complete the ceremony.
