"The Awakening" works as a moody ghost story thanks to strong performances and a creepily brooding atmosphere.
In England just after World War I, Florence Cathcart (Rebecca Hall) has a reputation as a professional debunker of the supernatural, busting seances for their parlor trickery. Then she meets Robert Mallory (Dominic West), who teaches at a remote boarding school where a boy recently died, apparently frightened to death by a ghost.
Florence sets up her tools and measuring devices, certain that it's a human hoaxster she's after. But strange things begin happening that have Florence second-guessing her skepticism and questioning her sanity.
