Even though Ti West's The Sacrament has finished filming, we know very little about the plot. Thankfully, Eli Roth, who produced the movie, revealed new details during a recent interview:

Via The Guardian: "I'm now producing a film called The Sacrament that Ti West produced and directed. He made a terrific film called House of the Devil, and had a great idea about a found footage docu-style horror movie set it a Jonestown type cult where we watch a mass suicide begin and the film makers are trapped inside. It's really, really scary."

The Sacrament stars Joe Swanberg (V/H/S), AJ Bowen (The House of the Devil), Kentucker Audley (V/H/S), Amy Seimetz (Tiny Furniture), and Gene Jones (No Country for Old Men). Release information is not currently available, but we'll report back when more details are released. Until then, take a look at the first photo below:
