A family's reunion turns deadly when its isolated home is invaded, and its members are murdered one by one—but one of the intended victims proves unexpectedly adept at organizing resistance. Writer Simon Barrett throws in some plot twists intended to explain away the clichés (killers wearing masks with tiny eyeholes, victims going off alone into the night or darkened rooms, etc.), but the movie still doesn't make much sense. Of course, it doesn't have to: People who go for movies like this never look that closely as long as the blood flows thick and fast, and director Adam Wingard makes sure that it does. Shoddy and cheap-looking (blame cinematographer Andrew Droz Palermo), this run-of-the-mill slash-'em-up flick has been floating around for two years looking for a distributor. Unfortunately, it found one.
