Jipaengja

Ian Lane wakes to find himself in an eerie house with no memory and only ominous strangers for company. He soon discovers that he's a member of a team of afterlife enforcers and that he was recently tricked into giving away an important key, setting off a chain of events that disturbs the entire balance of the beyond. It's up to the executors to set things right again, but between formidable new foes and demons from Ian's dark past, this job gives new meaning to the phrase "life or death."
