Oracle

Kate and Tony host a Halloween party at their beautiful, historic home. A guest, Lucy, brings a Ouija Board and guests gather around to play it. The group contacts a spirit, Zac, who takes a liking to Kate, and a DISliking to her husband, Tony. The board reveals secrets about Tony, causing friction in their marriage. Eventually, Kate is able to play the board alone, which leads to either possession, or insanity. It's up to the viewer to decide.
