At midnight, a bus with no known destination starts up in the thick fog.
Inside, a corpse hangs upside down from the windshield, gnawed to the bone, silently mocking the ugliness of the living. Outside the windows, evil spirits bare their claws and devour everything in sight.
When the deafening bang of a burst tire breaks the silence, the passengers tear off their masks of hypocrisy and shove and beat one another, trying to force someone off the bus as a "sacrifice to change the tire."
"He must have a way. He found a way out last time, too. He can't just stand by and do nothing this time!"
Under the greedy, vicious gazes of the others, Shen Yan lets out a helpless sigh and walks of his own accord toward the bus door that leads to hell.
They think the person they push off the bus is a scapegoat, but they don't know that the real rule of this bus has never been "sacrifice someone else and you'll survive."
Outside the bus are man-eating evil spirits; inside, man-eating human nature.
When morality crumbles and malice takes root, this last bus to the Underworld finally reaches its true hour of death.
