‘The Cellar’ Ending Explained – Does Keira rescue her daughter?

The Cellar Plot Synopsis

In this 2022 horror film, a family move into an abandoned Irish mansion but they soon regret their decision when their sulky teenage daughter Ellie goes missing.

Her parents, Keira and Brian, believing that Ellie may have run away, call the police, but as is usual in films of this sort, they are as much use as a chocolate teapot. At first, Ellie’s disappearance is treated as a ‘missing persons case’ but Keira soon begins to realise that her daughter may be trapped within the cellar.

Is Ellie in the cellar?

Well, the answer isn’t a simple one. After the power goes out in the home, Ellie calls her parents at their workplace. Keira tells Ellie to check the circuit box in the cellar but when the scared girl begins to descend the staircase into darkness, something strange happens. According to Keira, who remains on the phone with her daughter, there are ten stairs to the bottom. But as Keira listens to her daughter count each step, she realizes something is amiss when Ellie doesn’t stop at ten. Spooked by this, Keira immediately heads home but when looking in the cellar, discovers that Ellie is no longer there.

It would appear that Ellie is no longer in the cellar but this isn’t strictly true. She has, in fact, entered a different dimension, and this is something Keira discovers after finding the solution to a mathematical equation.

What has maths got to do with Ellie’s disappearance?

If you hated maths at school and thought it was the root (square) of all evil, then you were probably right!

Keira finds the equation in the cellar and notices that the symbols within match those that are above the doors in her home. She also hears a voice on a gramophone record reciting the equation.

She has no idea what the different symbols mean so to get the answers she needs, Keira gets in touch with a local mathematics professor. He tells her the equation points to another dimension, which is as confusing for Keira as it is for the viewer. When the Hebrew characters in the equation have been interpreted, she discovers they can be read as ‘Leviathan.’ According to ancient mythology, this is a monster that needs fresh souls to live, so the fact that it is connected to her home is not the best of news for Keira.

On further investigation, she also discovers the presence of Baphomet, another demon in her home, who guards a portal to Hell. This won’t be good for the home’s resale value!

Why is there a portal to Hell in the cellar?

In her quest to find out the answer to this question, Keira visits Rose, the elderly daughter of the home’s former owner, Dr. John Fetherson. She finds out that Fetherson made a deal with the devil when his only son died and that his deal backfired when the demonic trickster opened up a portal to Hell in the house. With the exception of Rose, all of Fetherson’s family members became trapped within this otherworldly dimension.

Why wasn’t the portal discovered earlier?

The portal can only be opened by Fetherson’s summoning chanting and as you can probably guess, this was the mathematical chant that was featured on the gramophone record. When Ellie played the record at the start of the film, she inadvertently opened up the gate to Hell in the cellar.

Does Keira rescue Ellie?

On returning home, Keira’s day gets worse when she realizes both her husband and son have been possessed by Baphomet. When they start reverse counting, the monster is summoned and he breaks through the cellar door. Somehow, Keira escapes the horned beast and makes it to the staircase in the cellar. She descends the stairs (which seem to go on forever) and finds herself in the other dimension.

Here, she discovers the presence of thousands of people, each one reciting numbers in a repetitive fashion. Ellie is one of these people and Keira snaps her out of the trance-like state that she has been put under. Taking her by the hand, Keira leads her daughter out of maths class…erm…Hell, and takes her back into the house. Job done! Or is it…?

Do Keira and her family survive the horrors of the Cellar?

After returning from Hell, Keira flings open the front door of her home. Her intention is to escape with her family but sadly, this is not to be. Instead of the freedom of the outside world, Keira discovers the house is still trapped in another dimension. Like the Fetherson family before them, the family are destined to live forevermore in their hellhole of a home, so there is no happy ending in this creepy horror flick.

  1. Yes, the house does exist in the real world, they got trapped in the other dimension where the house exists there too. At the end, when she opened the front door, they made it look like stairs goin upward – like walking up out of Hell and toward the real world again – why?

  2. Warning to everyone this movie is TERRIBLE. Please do not make a part 2 and leave the idiots in math class.

  3. There are many thriller horror movies which don’t have good endings and mysteries are left unsolved.

  4. There are many thriller horror moves which don’t have good endings and mysteries are left unsolved.

  5. Surprisingly creepy concept and well done film as usual for a Shudder original. It was a bit slow in the first 40 minutes but it needed time to figure out but overall creepy overtones and interesting film. No need for 2nd one but if they do it right I would watch.

  6. Why is it that, they’re all trapped inside,though it was making sense cause they were told by fetherson daughter that it was not just the cellar but the whole house,they failed to leave while they got chance but they still stayed,and i think fethersons daughter escaped the house just like keira had opportunity and could have abandoned her family but she chose to help them,so i guess they’re all trapped in forever,

  7. Good movie with a shocking ending. They definitely need a second movie, in which authorities investigate the disappearance of the family and Kiera looks for a way out of the dimension.

    Also believe the husband might have known more then he was letting on?! How was he enchanted? He started the summoning of the demon by try to destroy the symbols on the cellar stairs, did he mean too? He was too calm about the situation!

  8. The movie is not suppose to end the way it did because if Rose the daughter of Fetherson escaped Keira and her family should have escaped and she managed to save her daughter Ellie.
    The writer should do something about it, if there were no survivor understandable but now there is a Survivor which is Rose Fetherson

  9. The movie simply explained everything in detail. There’s no need for a part 2, maybe a series though. As I kept watching it, I already knew how it would end. I love it.

  10. Earlier on the horror movie ellie noticed the evil in there new home but her parents failed to understand or pay attention to ellie bad mood over there new home. I don’t think they are going to be free from that bond

  11. I don’t think there will be a part 2 so it looks like that family are trapped forever 🙁

  12. The writers must make a part 2 of this movie right. And im im wondering if the house is trapped in other dimension what about in the real world,does the house still appears.. please we need more explanation it cant just end like that. There has to be a way to close that dimension and go back to the real world

  13. Please make a cellar two…we need a better explanation of how or why they are still trapped inside…it was a great creepy movie though but i hate it when movies end in a way where they don’t explain much of what happened at the end.

  14. There’s got to be a part 2, The family can’t just be gone forever…Without no one seeing them ever again… Keira is the only one who isn’t enchanted.. Like reciting those number…She must be the solution to it all…The film can’t just end this way…

  15. Do you think there will be a part 2, because they have to solve this problem. If not this story is sucks.
