Bart Simpson struggles academically, failing to convincingly fake a book report on "Treasure Island." At home, his sister Lisa's academic success contrasts with his difficulties. Desperate to improve, Bart initially avoids studying, then fakes illness to escape a test. Realizing his tactics aren't working, he makes a deal with classmate Martin for help. Facing imminent failure, Bart prays for a miracle, which comes as a snow day. He resists the temptation to play, studying instead. In a surprising turn, a small piece of historical knowledge nudges Bart's test score to a barely passing grade, marking a rare academic victory for him.
