An offbeat thriller, Jerry Fletcher (Gibson), a conspiracy-obsessed New York cab driver, sees evidence of sinister plots in even the most ordinary places.

Alice Sutton (Roberts) is a bright, albeit skeptical justice dept. attorney. 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 its big” Jerry says. What we know is that Conspiracy Theory is big entertainment.
