Five months after being orphaned her cousin Noah and Uncle Tom take her in. Things seem normal at first but quickly take a turn for the worse. Micah begins to experience black outs, the "missing time phenomenon" and other supernatural manifestations. When it becomes violent, Micah and those around her come to the disturbing realization that something is after her - intent on harming her and those closest to her.

A young journalist named Jin Maddison has traced the origin of many Christmas traditions to a remote town in the Midwest called Selah. Years ago another famous journalist died in an accident there while investigating the same story. Jin travels to Selah hoping to unravel the mystery, suspicious of a darker truth behind the festive holiday. Upon arrival she's stunned by the lack of decorations, lights, and signs, as well as the refusal of most locals to even talk about 'Christmas'. After a violent encounter she's saved by Private Investigator Amy Carson, who is trailing several Missing Persons cases that have led her to Selah. As they continue prying, they realize that the secrets Selah is hiding are far more terrifying than they could've ever imagined.
