Li Mo, who was dying, signed a contract, willing to go to purgatory in exchange for the health of his wife and daughter. Unexpectedly, the core of purgatory is actually the despair ward where his wife is located! He became a ghost that no one could see, watching his wife and daughter sink in pain and debt - the so-called "well-being" was nothing but a cold scam.
While wandering, he glimpsed more souls being tortured in purgatory on earth. What's even more shocking is that the flawless guide actually has the cuffs of his hospital gown exposed under his suit! A mountain of abandoned deeds reveals numerous scams.
When his wife tore up his daughter's last painting, and when the debt collector threatened to kidnap his daughter, Li Mo's despair turned into his final strength. He carved a huge "?" On the tiles in the corner of the ward. This bloody and tearful questioning leads directly to the lies of passers-by and the rusty iron door at the end of the corridor that hides secrets. The soul made its final roar in the core of hell.
