The Awakening (2011)

A skeptic's faith (or lack hereof) is put to the test in the old-fashioned ghost story The Awakening (2011). Rebecca Hall stars as Florence Cathcart, a professional paranormal investigator in post-WWI England who delights in debunking claims of the supernatural. But when she visits a boarding school supposedly haunted by the ghost of a former student, Florence experiences some things that even she can't explain. 53 minutes in, after getting out of the bath, Rebecca drops her towel and exposes her left breast, a scene that may conjure up some things that go bump in your pants.
