The episode begins with Bart Simpson and his friends at Springfield Elementary School, where they are excitedly discussing the upcoming Springfield Elementary School's annual track and field day. Bart is particularly enthusiastic about the event, as he sees it as an opportunity to showcase his athletic skills. However, his excitement is dampened when he learns that the school has introduced a new rule: students must drink a special milk that is supposed to enhance their performance.

As the day of the event approaches, Bart reluctantly drinks the milk, which is marketed as "Super Milk." He initially feels a surge of energy and confidence, believing that it will help him win the race. However, the effects of the milk soon take a turn for the worse. Bart begins to experience strange side effects, including increased hyperactivity and a lack of focus, which ultimately hinder his performance.

Meanwhile, Lisa Simpson, Bart's sister, becomes suspicious of the milk's effects. She starts to investigate the ingredients and discovers that the milk contains a mysterious additive that could be harmful. Lisa's concern grows as she witnesses Bart's erratic behavior during practice sessions. She tries to warn him, but Bart brushes off her concerns, convinced that he will still perform well.

On the day of the track and field event, the school gym is filled with students, parents, and teachers. Bart, fueled by the Super Milk, takes to the track with a newfound energy. However, as the race begins, he quickly realizes that he cannot control his speed. He zooms past his competitors but struggles to maintain his balance, leading to a series of comical mishaps.
