Born with psychic senses and mistaken for insane, a young man is driven off the mountain. He stumbles into a job as an underworld outsourced customer service agent. That’s when he discovers the “hallucinations” that plagued him for 20 years were actually hell's uncensored live feed! To save his master, who’s now marked by the Demon-Slaying Sword, he’s forced on a darkly humorous, bone-chilling quest: to reconnect the realms of the living and the dead and unravel a two-decade cold case.
