In the twelfth year of the Republic of China, Qiancheng in southwest Guizhou.
A disease called "plague" swept through the city, killing countless people in three days. The people were terrified and the government was in dire straits.
Shen Qingluo, a Miao poison doctor, was accused of being a "poisoner" and was thrown into prison to be executed on a day-to-day basis.
Gu Yanzhou, the young master of the Gu family who returned from studying abroad, proposed to use her voodoo skills to fight the epidemic.
"How many people can you cure with your science?" "Your voodoo is just a trick of pretending to be a ghost."
From questioning each other to fighting the epidemic together, from prejudice to heartache, from use to protection——
She uses poison to save people, and he uses medicine to protect the city.
However, behind the epidemic, there is an undercurrent surging. Can they work together to uncover the old case of family extermination fifteen years ago and the man-made conspiracy at the source of the epidemic?
"You save others, who will save you?"
"Then... Please excuse me, Master Gu."
