Gregg is an asshole, with an asshole that talks. He sees the great Dr. Watson for the cure. And meets another of his patients, Briana, with a pussy that talks. They fall in love. Why? Communication, obviously.
The pieces fit. The puzzle changed. Fish is a man who likes to watch. He just can't talk, touch or feel. One day a girl turns up dead in the park. Fish may have seen too much. We could tell you more, but then we'd have to kill you.
