Two young missionaries are forced to prove their faith when they knock on the wrong door and are greeted by a diabolical Mr. Reed, becoming ensnared in his deadly game of cat-and-mouse.

Grant stars as Mr. Reed, while Sophie Thatcher and Chloe East play the Mormon missionaries, Sister Barnes and Sister Paxton, respectively. Topher Grace also stars in Heretic as Elder Kennedy.

Written and directed by Scott Beck and Bryan Woods (Haunt, 65), Heretic opens in cinemas on November 29.
