"The Devil You Know" is a story about Julie Collins and her unfortunate predicament. For most of her life, she resided in the city, and spent a lot of time with her best friend Marie-Do. However, due to her cancer-stricken father, Julie's parents decide the best way for him to go is living out his days in the comfort of his childhood house. When they arrive, Julie admires the grand old house, dusty but lavish just the same. A second glance at the ornate front door has her shaking in terror, when the image of an angel morphs into a scythe-bearing child demon.
