2019 film directed by Richard Stanley

Two brothers return to the cult they fled from years ago to discover that the group's beliefs may be more sane than they once thought.

In the middle of a routine patrol, officer Daniel Carter happens upon a blood-soaked figure limping down a deserted stretch of road. He rushes the young man to a nearby rural hospital staffed by a skeleton crew, only to discover that patients and personnel are transforming into something inhuman. As the horror intensifies, Carter leads the other survivors on a hellish voyage into the subterranean depths of the hospital in a desperate bid to end the nightmare before it's too late.
