Heretical Conclusion Explained: What is the One True Religion?

This article contains spoilers for Heretics. If you’re here to find out if there’s a post-credits scene, there isn’t.

Heretic was always going to be a film that relied on its performances. Going in, we assume it will be a chamber piece focusing on two Mormon missionaries trying to convert an old man to their religion, which will require some heavy acting from all three leads if the audience is to stay engaged. These performances are all there in spades, but in Act 3 we know that things are not as they seem, and we want to go far beyond a cozy living room chat about religion.

Sister Barnes (Sophie Thatcher) and Sister Paxton (Chloe East) arrive at Mr. Reed’s (Hugh Grant) home just as a blizzard begins to hit. The seemingly friendly man invites the freezing missionaries into his living room and insists that his wife is in the kitchen baking a blueberry pie. Able to smell the confection, the two girls reluctantly enter the home with the caveat that Mr. Reed’s wife is to join them as soon as she finishes baking.

Unfortunately, Mrs. Reed completely invented, Mr. Reed made the scent with a scented candle, and he has a host of tricks and traps in his unhinged house of doom, which he insists are specific to challenging faith to find the one true religion.

Heretical ending explained

One important thing to know going into Heretic is that there isn’t really a second act. You could kind claims to be there for the brief window when Reed traps the girls in the basement and Sister Barnes is still alive, but it mostly just doesn’t exist. One moment the three are having a spirited debate about faith, who is right, and whether or not Mr. Reed should convert, and the next, both sisters are trapped in a murder cellar staring down a supposed prophet.

Reed is able to trap the sisters in the basement by presenting the illusion of choice. A big chunk of the film’s runtime is Grant pulling out every ounce of charisma (which, after years of his films, we know is quite a lot) while cheerfully telling the girls they’re free to leave at any time. But that freedom was never there, and the choices were all illusions.

After the girls end up in the basement, Sister Barnes has had enough. She begins to actively challenge Mr. Reed as the more timid sister looks on. The drop is Reed’s prophet trick, where a screwed-up woman is pulled from yet another unseen corridor in the basement of Hell, fed poison, dies, and then miraculously returns to share what God told her.
