Pyewacket [Blu-ray]

After her father's death, resentful teen Leah (Nicole Mu?oz) is left with her mentally ill mother (Laurie Holden). Forlorn, she turns to occult magic, but when she foolishly conjures a spirit to kill her mom and then immediately attempts to reverse the spell, she ends up summoning a terrifying presence. Written and directed by Adam MacDonald.
