The Sacrament, Ti West’s found footage horror film, tracks an innocuous visit gone awry. Kentucker Audley, Joe Swanberg and AJ Bowen star as a coterie of photographers who visit Audley’s sister, played by Amy Seimetz, on the Eden Parish commune, where she has lived since completing her rehab program. Turns out the place isn’t as forgiving as Audley and co. suspected. The Sacrament hits theaters on May 1, and you can watch the red band trailer above.
