The Setup: OK, OK — this one isn't directed by Shyamalan, but he's responsible for the story and it shows. Five strangers find themselves trapped inside an elevator in an office building, and every time the lights flicker out, someone is viciously attacked in the dark. As tensions (and injuries) rise, they try to figure out who is responsible while Detective Bowden (Chris Messina) desperately attempts to save them on the outside. Finally everyone is picked off except for a mechanic named Tony (Logan Marshall-Green).
The Twist: Except not everyone is actually dead! The old woman in the elevator (Jenny O'Hara) comes back to life and reveals herself to be the devil. The literal devil. As she moves to attack Tony, he confesses that he was the driver behind a hit-and-run five years ago that killed Detective Bowden's family. The confession releases the hold the devil has over him, so the devil disappears and spares Tony's life.
The Verdict: Once you can get past the heavy-handed religious themes and a few hokey scenes, the old woman morphing into the devil is a real shock. Shyamalan might not have directed it, but the story is genuinely chilling.
