Legend has it that on Christmas Eve, Santa Claus is accompanied by a creature called Krampus. While Santa brings gifts to well-behaved children, Krampus deals with the misbehaving ones. But is this just a story? As the holiday season approaches, misbehaving children in a suburban area start disappearing, suggesting that the creature might be real. In this sequel to “The Night Shift,” supernatural detectives Rue Morgan, Claire Rennfield, and their skeletal companion Herbie West must unravel the mystery, rescue the children, and confront the menacing Krampus.
