Sixteen-year-old Jamal Wallace plays basketball with his friends in New York. A recluse, William Forrester, lives on the top floor of the building across from the court. The kids regularly notice him watching them. One of the boys dares Jamal to sneak into the apartment and retrieve an item. Jamal takes a letter opener only to be surprised by Forrester and inadvertently leaves his backpack behind.
Forrester later drops Jamal's backpack onto the street. Jamal returns home to find that Forrester wrote notes in Jamal's journals. Jamal returns to Forrester's apartment and asks him to read more of his writing. Forrester tells him to begin with 5,000 words on why Jamal should "stay out of my home," which he completes and leaves on the doorstep the following day. Jamal returns the next day and is invited inside.
