Train No. D444, also known as "tribulation", some people are destined to have tribulations, either because of their birth date, or because of mistakes or regrets in previous lives, or because of bad things they have done in this life, or...
As the conductor of train D444, Su Yang is also the controller of mankind's disaster.
On the train, he saw the fate of people and what others could not see.
Su Yang controls the fate of mankind at night and inherits his grandfather's legacy as a corpse cleaner during the day.
Corpse cleaner is an ancient and mysterious profession. Whenever there is a murder involving jumping from a building, lying on a train, dismembering a body... Or other murders that cause the body to be torn apart, someone needs to be assigned to clean up the body and the scene.
Etc! ! !
How come the woman in red with mutilated limbs I saw on train D444 last night looks exactly the same as the woman whose body was cut into pieces by her husband today? ? ! !
