What's The Seance about? Here's a hint:
Abby has always been fascinated by the paranormal, but after an ill-fated séance, she discovers not all Spirits are benign. A dark entity unleashed during the summoning sets out to destroy Abby, and within days, she loses her best friend, incurs the wrath of her parents, and becomes a prisoner in her own home. With time quickly running out, she assembles an unlikely group of helpers: the most hated guy in school, a retired psychic, and the cute clerk from her favorite bookstore. Unless the demon is defeated, Abby and her new baby brother won’t stand a chance.
