The synopsis: A pair of young, imaginative twin brothers named Lukas and Elias excitedly welcome their mother home after she's had a cosmetic surgery procedure on her face. She treats the boys rather coldly, and with her face wrapped almost entirely in bandages, they begin to suspect that the woman who came home isn't their mother at all.
The twist: In an effort to get the "imposter" mom to reveal who she really is, Lukas and Elias superglue her to the living room floor. They begin to burn down their home to pressure her into telling the truth, which is when she begs Elias to stop doing all this so they can move on from his brother's death — Lukas has been dead the whole time, having passed from a tragic accident before his mom returned home. Elias refuses to believe her, and the house burns down around them, killing them both.
The amount of damage it'll do to your psyche: 🔪 🔪🔪🔪 (an extra knife for the sound of the mom ripping her superglued skin off of the floor)
