The Exorcist: Believer will be available to purchase digitally less than three weeks after the film debuted in theaters. A legacy sequel to The Exorcist, the film centers around single father Victor Fielding, whose daughter, Angela, is possessed by a demon named Lamashtu. Working with another family whose child was possessed, Victor ends up going to Chris MacNeil from the first film in hopes of saving the children.
