Mercy just wanted a quiet evening with her folks after a hard week at work, followed by a rather eerie phone call. Instead, she finds herself alone in the old family home as the dark descends. Unfortunately for Mercy, she's not alone for long. For reasons she can't understand, she finds herself surrounded by men in masks with an unclear but obviously sinister purpose. What Mercy does know, is that her situation is dire and that she can't let them take her. No matter what.
