Sigourney and Murphy are two physicists who investigate paranormal activities in order to disprove them. The movie starts out with some pretty normal bump in the night cases, but builds upto the point where they meet De Niro's charater, who is the USA's biggest psychic just come out of retirement. The university where Sigourney works conducts controlled experiments on De Niro to try and prove his powers are real, but there are a few twists and turns as the results are about to come out. Fairly slow burning film, but interesting topic, well acted and keeps you involved. Just a bit too slow for my liking.
