The synopsis: Three friends decide to rob a blind veteran who just won a massive settlement from a young, rich woman who killed his daughter in a car accident.
The twist: Technically Don't Breathe has seven big twists, all of which you can read here. The biggest one, though, is that "The Blind Man" (yes, that's the name of his character) kidnapped the woman who ran his daughter over, and has held her hostage in his basement for months. On top of that, he impregnated her with his sperm (via turkey baster, naturally) so that she could bear him a child to replace his late daughter.
