In modern cities, the strong regret, obsession and regret in the hearts of living people will distort reality and project an illusion called "echo".
Shen Zhiwei runs a niche trauma psychological consulting firm, and she can see the fragmented echoes of obsessions.
She has no superpower to dispel illusions, nor can she rewrite the past.
One commission after another comes one after another: a widow trapped in the phantom of her late husband, an old mother living in the phantom of her son, a businessman trapped in the past of failure...
The illusion is just a shell, the real crux is buried deep in the heart.
Crisis intervention social worker Lu Yan met her during a case. The two tested each other, were wary of each other, and faced the guilt, lies and unwillingness of human nature together.
At the same time, the echoes of Shen Zhiwei's own obsessions that have been buried for many years are quietly surfacing.
