The End is Near (2014)

"It's dawn. Precisely 5:26 in the morning, the 13th of February, 2014. We're just a few miles outside the compound of a group that refers to themselves as 'The Church of the Sidways Circle.' Their leader, a man who calls himself Hezekiah, has agreed to allow our crew to document him and his followers as they embark on a ritual of purification in preparation for an event that they are calling 'The End of the World.' An event which Hezekiah has predicted will occur at precisely 12:24 in the afternoon on February 14th of this year. For Hezekiah and his followers, the end is near."

Unfortunately the movie The End is Near is not yet available on HBO Max.
