Millennial entrepreneurs, Max and Drew, run a popular webcast that streams “live exorcisms” that are, in fact, elaborately staged hoaxes watched by millions. However, their fortunes take a turn when during one of their webcasts, Drew's fiancée becomes mysteriously possessed by a real demon that takes the crew hostage. In front of a rapidly growing global audience, the demon subjects the crew to a series of violent and humiliating challenges that expose dark secrets they have been hiding from each other.
