The film is based on the true story of the exorcism of Emma Schmidt, an American woman who was allegedly possessed by a demonic entity. 

The plot revolves around two priests, Theophilus Riesinger (Al Pacino) and Joseph Steiger (Dan Stevens), who must overcome their differences and work together to perform a series of dangerous exorcisms on Emma to save her soul. 

The Ritual is inspired by the 1935 book Begone Satan!, which has been at the center of faith-based debate for nearly a century. The original account of the events went on to inspire The Exorcist book and William Friedkin’s famed 1973 film.

The Ritual is an authentic portrayal of Emma Schmidt, an American woman whose demonic possession case remains the most thoroughly documented exorcism in American history.

Ashley Greene, Patricia Heaton, Abigail Cowen and Ritchie Montgomery also star in director David Midell's feature that hits theaters this month.

Prorom is releasing The Ritual in Romania (on May 30), Bulgaria (June 6), Hungary (on July 3) and Czech Republic & Slovakia (on July 10).
