Cheng Xi is a photographer obsessed with capturing "soul moments", but when his career is at a low point, he meets Su Yan, an eccentric biologist who stands in the rainstorm and talks to the raindrops.
Su Yan was cold and distant, refusing to be anyone's model until Cheng Xi discovered his secret: he could see the souls of the dead, including his lover who died three years ago.
When Cheng Xi's camera accidentally captures an image of a spirit that shouldn't exist, the two are forced to face a phenomenon that science cannot explain. In the midst of doubts and conspiracies, between the rational scientist and the intuitive artist, whoever breaks the wall first will see the light first.
