Plot summary
Douglas Hanson, or Dougie as he is referred to by his bestfriend, begins the story by talking about his best (and only) friend, Andrew (Andy) Morrow. Athletic and popular, Andy is very different from socially inept Dougie, yet the two find things to talk about. However, as the story progresses it becomes evident that Andy and Dougie's friendship is not what it seems to be at first. Dougie also is suicidal and has an obsession with a train set he inherited from his grandfather. He creates, a town involving the trains, called Madham and obsessively builds a replica of the Golden Gate Bridge using match sticks in the basement of his parents' home. Dougie appears to be unaware he has some form of mental illness (potentially PTSD, schizophrenia, pyromania), although what type of mental illness he struggles with is never discussed. He often views others as being different or abnormal. Dougie claims he is not a troubled youth, but others seem to see him as such, and he engages in troublesome activities: stalking and prank calling. As the book progresses, Dougie mentions attending (and skipping) therapy sessions and not taking the medications he had been prescribed for anxiety. After an incident at school, Dougie eventually admits to his psychologist that he hasn't been taking his medications and is also forced to remember a fateful night at the Tuttle Place. Dougie initially seems to come to terms with this reality during the therapy session, but afterwards convinces himself the illusory manifestations are also real.

In the end, he sets a series of events in place that have dire consequences for him that lead to his hospitalization. However, it is debatable as to Dougie's fate since he was hospitalized at the "Madham Burn Unit". He also mentions the hospital smells of burning plastic, referring to the plastic people in Madham, present when he set the town on fire, and he wants to find his grandfather, to see if he is mad about the train. Whether it is his imagination that leads him to smelling burnt plastic and seeing "Madham Burn Unit" or otherwise is not revealed.
