Below, we break down what happens in the ending and how it differs from the book.

The entire movie is meant to keep the audience guessing.

The strangers claim that one family is chosen every so often to decide the fate of all of humanity.

Collective visions have seemingly brought these four disparate individuals together to deliver the challenge.

They start with Redmond and work their way up to Leonard.

Each death is meant to unleash a plague upon the world.

They are all just deluded conspiracy theorists who found purpose in shady internet chatrooms, he claims.

Eric, however, is more empathetic and subject to suggestion.

The events play out rather differently in Tremblay’s book.

First of all, Wen dies from an accidental gunshot during a scuffle with Leonard in the cabin.

Choice wasn’t a factor.

The outcome of this sequence is completely left out of the movie.

There are also some cosmetic changes.

But the biggest change beyond Wen’s death is how the movie interprets the ending.

The Cabin at the End of the Worldleaves the reader to draw their own conclusion.

The fathers, mourning the loss of their child, refuse to kill each other.

Instead, they drive away from the cabin with Wen’s body in the back towards an uncertain future.
