Two paranormal skeptics investigate a well-know psychic who is making a comeback after many years of absence. Over the course of their investigations, their understanding of the world is challenged as old traumas threaten to rear their heads.
The film follows a physicist (Murphy) and a university psychology professor (Weaver), both of whom specialize in debunking supernatural phenomena, and their attempt at discrediting a renowned psychic (De Niro) whose greatest critic mysteriously died thirty years prior.
