Song Mu, an abyssal demon disguised as an ordinary college student, lurks in the human world just to find the lost "primordial fire". One night, he was involved in a weird truth or dare game. The participants were all "white-eyed wolves" with their own agendas: a scholar who betrayed his mentor, a mercenary who betrayed his teammates, and a powerful man who killed his relatives. The rules of the game are cruel, the liar will be deprived of his soul, and the winner can realize a wish. Song Mu relied on the devil's insight and resourcefulness to navigate step by step in the maze of lies. Not only does he want to expose everyone's hidden evil, but he also wants to find out the real operator behind the game - the ancient evil god who is trying to use human greed to devour the world. In this brain-burning game of life and death, Song Mu carried out judgments in the name of the devil, using his wisdom to send hypocrites to hell one by one.
