Mr. Burns is gravely ill and needs a blood transfusion, and Bart is the only compatible donor. Homer encourages Bart to donate, anticipating getting a big reward from Burns in exchange for saving his life. When Bart gives his blood and no reward comes (only a thank-you card), Homer gets angry and writes a nasty letter to Burns. Marge intervenes and talks Homer out of mailing the letter. However, Bart, not perceiving that Homer had second thoughts, discovers and mails the letter. Chaos ensues as Homer and Bart try to retrieve the letter before Burns receives it.
