Georgie Fishman hasn't been able to sleep for six nights. After several hours of television, he decides to call his therapist, Dr. Miller, to whom he explains the problem. Earlier that week, a strange man named Harry Kellerman called Sally, his girlfriend, and told her that Georgie was a violent man with a wife, three kids, and several social diseases. But Georgie has never even heard of Harry Kellerman.
He hangs up when Miller doesn't offer any solace and begins to study his so-called List, a sheet of paper with everything he knows about the man and a few guesses about who he might be. Suddenly suspicious, he decides to call his father and mother, but it's not them. In between strange dreams which feature his own suicide, a Jamaican version of Miller, and more, he calls Miller again out of suspicion. He, too, is innocent.
Calls to his first girlfriend and from his best friend and fellow musician don't help either. Finally, he calls his estranged sixteen-year-old son for comfort, but the boy, perhaps the only kid in the entire country who hates Georgie's music, just gets annoyed.
Finally, after he realizes that he loves Sally, he calls her again. But she recognizes the voice immediately and hangs up — she does not, she says, want to talk to Harry Kellerman again. Next to Georgie on the bed sits Dr. Miller, this time as a ski instructor, and they set out for a two-mile trip down the slopes.
