A darkness descends over Emily as she becomes obsessed with the board’s power of divination and ability to summon spirits. Desperate to help his fiancé, Christian seeks the advice of occult expert Alexander Babiaste (Jamie Campbell Bower). But Babiaste has secrets of his own, including his connection to a modern-day coven of witches. A dangerous game begins as each swing of the pendulum puts Emily’s very soul at risk.
