Jerry Fletcher sees conspiracies everywhere. One has turned out to be true. Now his enemies want him dead. And she's the only one he can trust.
New York cab driver and conspiracy buff Jerry Fletcher (Mel Gibson) knows about the secret movers, shakers and assassins who really control things. Trying to put Justice Department attorney Alice Sutton (Julia Roberts) in the know, he's run out of her office. Soon both will run for their lives.
The two stars conspire for suspense, romance and twists that click like a rush-hour taxi meter. A crackpot theory in the newsletter Jerry publishes may be true. Cryptic Dr. Jonas (Patrick Stewart) and his men aim to quash it - and them too. "I don't know what I know but I know that it's big." Jerry says. What we know is that Conspiracy Theory is big entertainment.
