During the demolition of an abandoned cinema in Qingqu County, workers discovered a female remains in the wall behind the screen.
Next to the remains is a 1993 movie poster. The signature in the lower right corner belongs to the poster artist Zhou Qishan who mysteriously disappeared eight years ago.
His son Zhou Yan returned home from Chengdu. He originally just wanted to prove that his father was not a murderer, but he found a code word in the poster consisting of misplaced colors:
She's not the first.
A modified date of birth, a never-released movie, her mother's 33-year concealment of her birth experience, and an old tape recording seven knocks gradually led Zhou Yan to his family.
Everyone said that only two people died that night.
But after the seventh tap in the recording ended, his most trusted relative said:
"Don't open it, she won't be able to come out even if she wakes up."
