Natalie is a tired and unkempt student who works as a radio station host for the tacky KFDL 106 FM radio station. Working the night shift on Halloween, she answers endless calls from her listeners searching for the perfect Halloween horror story, but none of their dull stories seem to interest her.

But Natalie’s interest soon turns to dread, as she realises that this caller knows more about her than she’d like them to know. As Natalie becomes more determined to stop this caller in his tracks it becomes evident that not everything may be as it seems. Why is Natalie so adamant to stop him from finishing his story? How does he keep calling back? And what will happen when the caller loses his patience...
