"Did you dream about the murderer?"
High school student Sang Yu can sneak into other people's dreams and see the truth about death.
Serial murders occur frequently on campus, and the dead are all "evil people" - domestic violence, bullying, corruption...
As their investigation deepened, Sang Yu discovered that the same figure flashed through every dream: the transfer student who always smiled at him - Lin Qincheng.
Memories begin to split, time goes backwards, the summer disappears, and the truth of ten years ago emerges.
Who killed our summer?
Lin Qincheng looked at Sang Yu with a smile: "Now we are accomplices."
It turns out that it wasn't just that summer ten years ago that was burned to death.
The rain fell like a judgment, but it could not wash away the blood on his hands.
