Whacked-out New York cabbie Jerry Fletcher (Gibson) writes a newsletter on conspiracy theories, which he finds in every possible place and situation. Naturally, he doesn't keep his thoughts to himself and exasperated Justice Department attorney Alice Sutton (Roberts) is stuck listening to the love-struck fool. But as the saying goes just because you're paranoid doesn't mean they're not out to get you. Sure enough, one of Jerry's conspiracies turns out to be true and suddenly he and Alice are being pursued by CIA shrink Dr. Jonas (Stewart), who's not what he seems to be either. Gibson's more geek than hero but appealing regardless, as is heroine Roberts. Another successful, enjoyable, and highly profitable, teaming of Donner, Gibson and producer Joel Silver.
