Dong Qing is a perfect representation of an “utter loser”; a 24-year-old underachiever, he lives paycheck to paycheck, takes on odd jobs here and there to pay for his tiny apartment. However, he has an extraordinary secret — he has the ability to see and communicate with the beings of the underworld.

One day, Dong Qing manages to land himself in a job as a night shift shop assistant at a 24-hour convenience store called the No. 444 Convenience Store. However, Xia Dong Qing has no idea that the store is the nexus between two different realms. In other words, it’s a ‘soul station.’ The ferryman Zhao Li has been stationed there for the past 500 years. By day, humans frequent the store. By night, all kinds of spirits haunt. Souls of the deceased depart from here to the netherworld but there are some who refuse to leave as they have some unfinished businesses.
