Dennis Jennings (Steven Wright) is an introverted daydreamer, sleepwalking through life. He is a professional waiter and has an equally-dull girlfriend, Emma. In an attempt to release his pent-up feelings of isolation, he begins seeing a psychiatrist (Rowan Atkinson), only to discover that the doctor is somewhat less than interested in what he has to say. After finding his doctor sharing his intimate secrets with a group of fellow psychiatrists at a bar, and then finding that his girlfriend is cheating on him with the doctor, Dennis decides he has had enough. He hunts the doctor down in the woods and shoots him, ending up in jail with an equally uncaring prison shrink.
