Former lie detector expert Shen Tingyan receives the diary of his late girlfriend, Lin Wan, and follows its clues to the isolated town of Wangchuan. Here, hot springs steam and everyone keeps their secrets close. He soon discovers that the town’s “Pool of Lies” can make spoken words come true, but at the cost of devouring memories.
When the first wish comes true and everyone’s memories begin to twist, Shen Tingyan is plunged into a crisis of trust. The gentle doctor Gu Qingzhu offers to help, yet always stops short of speaking at crucial moments. The mysterious mayor Wei Zhinian makes his advances with elegant charm, while secretly manipulating the memories of the entire town.
As the investigation deepens, Shen Tingyan discovers a startling connection between Lin Wan’s disappearance and a mass amnesia event twenty years ago. In a town where the truth vanishes and lies can come true, he must use the final truth to fight back against altered memories. When the pool churns and the fog lifts, what awaits him is not only a brutal truth, but also the ultimate choice between existence and oblivion.
This diary is both a cry for help and a death warning. In a town where everyone is forgetting, he alone must remember it all.
