A film like “Locked” lives and dies by its ability to entertain us with images of a man banging on tinted windows for help while he faces the prospect of being hurled off the roof of a parking garage. And on that, it delivers.

A compact, tense movie with only five speaking parts, this effective thriller taps a bit into contemporary cultural divides and social anxiety to make the most of its cat-and-mouse game.
