After getting in a car accident, Eun-soo wakes up and meets a mysterious girl who takes him to a fairytale-like house in the middle of the forest, where she lives with her siblings and parents. Everything is bright and colorful, there are toys everywhere and sweets for every meal. Jung-soon is invited to stay with the family but soon discovers that there is no way of leaving and that there is more to the children than meets the eye.
Not to be confused with the 2013 Asylum film of the same name.
This movie contain examples of the following tropes:
- Alien Geometries: If you try to leave the house, you'll only end up right back.
- Anti-Villain: Despite his hell of a temper and frequent Kick the Dog moments, Man-bok is ultimately trying to protect his sisters and start a family.
- Bigger on the Inside: The attic stretches on for miles.
- Crapsaccharine World: It's a beautiful house straight out of a fairy tale — just don't think about leaving.
- Fingore - Manbok chops off the "father"'s fingers after he feels neglected.
- I'm a Humanitarian - The children's "father" is cooked and fed to Jung-soon.
- In Name Only - There are certain elements borrowed from Hansel and Gretel but overall the main storyline has little in common with the original fairy tale.
- Karma Houdini - The kids never receive any punishment for kidnapping and ultimately murdering various "parents".
- Older Than They Look - The kids have been kids for a very long time.
- Transflormation: The deacon's wife is turned into a tree.
- Would Hurt a Child - The deacon (who's also a pedophile).
- Your Mind Makes It Real - "Santa" tells the kids that their dreams will come true if they only imagine it...
