If you have a creepy Ouija board story, this will surely top it. Above is the trailer for Ouija: Origin of Evil—a period thriller set in 1965 Los Angeles.
The plot goes like this: A widow and her two daughters are running a seance business, scamming people of their hard-earned cash as they search for loved ones caught in the afterlife. Then all of a sudden, one of the daughters becomes possessed, presumably for tampering with the spirits. Joke's on you, mom!
