Gu Xiaoxian was originally a small citizen. He was briefly near death due to an accidental car accident. When he woke up, he was qualified as a "temporary ghost errand in the underworld". Forced by his duty as a ghost, he must assist the underworld in handling supernatural incidents and escort the ghosts wandering around the world to justice. However, Gu Xiaoxian is naturally afraid of ghosts, and his partner is the talkative "Huang Banxian". One of them is a coward and the other is funny, and they laugh constantly during the supernatural investigation. In addition, Lin Yueru, a supernatural Internet celebrity with a ghostly physique, joined the team, and the novice ghost team became more and more familiar with each other. They rescued trapped souls in complicated and confusing cases, and gradually discovered dark cracks in the order of the underworld. After a series of absurd, bizarre and meaningful cases, Gu Xiaoxian finally grew up in the joyful bickering and dangerous tests, leading his teammates to face the ultimate mystery behind the human heart and the ghost world, and finally complete self-salvation.
