While the title alone may grab most people's attention, the Korean thriller series is sure to pack quite the punch when it comes to suspense and keeping viewers on the edge of their seats.

More recently, posters for the series were released with the tagline: "Dear guest, you are not welcome." So, it's safe to say that the series will most certainly have the same tone as the ominous message.

The series unfolds in a remote countryside location where the owner of a rural motel has his peace disturbed by another guest. Soon, cracks start to appear in the tranquil countryside setting but all is not quite as it seems as the supernatural starts to take over the motel.
