A bizarre car accident caused Shen Nian, a doctor of folklore, to accidentally travel into an ancient shadow puppet show. Here the sky is the curtain, the earth is the stage, and the sun, moon and stars are all props. Everyone was performing a forbidden play called "July and a Half" according to the fixed script, and she was just a passerby who could not live for three days.
Whenever she tries to escape, she encounters "dramatic modification" - amnesia, stiffness, and even disappears out of thin air. What's even weirder is that when he was young, his grandfather was actually the "operator" of this play. In order to seal something indescribable, he trapped everyone in the play for hundreds of years.
Shen Nian discovered that the only way to break the situation was to become a new "opera singer." She used modern folklore knowledge to rewrite the taboo old drama into a warm new one. However, when the stage lights came on, she finally saw clearly - the "audiences" sitting under the stage were no longer alive.
