The Blood Pool Hell, the thirteenth level of the legendary Hell.
Six mysterious cases of spontaneous human combustion triggered a horrific past forty years ago.
Forty years ago, a tragic conflict occurred in a factory deep in the mountains, but the scene was very strange: no wounds could be found on the bodies of all the dead people, but the ground and the room were all splattered with blood, and the whole scene was like the "Blood Pool Hell" in the thirteenth layer of hell. The scene should have been at the scene of a young woman but the strange disappearance, just left a piece of the ground burned black traces.
Forty years later, Zhou Yuan, a black car driver in a small town, witnesses in horror a man spontaneously combusting in front of him, also leaving only a scorched mark on the spot.
Soon Zhou Yuan realizes that the blood he spills out will inexplicably burn!
In order to escape the fate of dying by spontaneous combustion, Zhou Yuan and his friends start trying to find the truth behind the strange disease.
But as the connection between the two events before and after decades becomes clear, a truth that surprises everyone is slowly revealed. Sometimes, learning the truth doesn't mean the problem can be solved.
Maybe it's just the beginning of a bigger problem.
