The Computer Wore Tennis Shoes

Dexter Riley and his classmates at Medfield College encounter a significant hurdle as they struggle to acquire a vital computer for their studies. This need sparks the idea to seek help from wealthy businessman A. J. Arno.

In an attempt to resolve their dilemma, the students persuade A. J. Arno to donate an outdated computer to their college. However, unbeknownst to them, this simple act is laced with ulterior motives linked to Arno's gambling operations.

During a storm, Dexter is shocked while working on a computer, which magically enhances his mathematical abilities. This electrical jolt allows him to absorb and retain vast amounts of information quickly and accurately.

With his newfound talent, Dexter leads his college's team in a high-stakes televised quiz tournament. The entire college's hopes hinge on his exceptional intellect for securing the coveted $100,000 prize.

As the quiz tournament progresses, Dexter accidentally triggers the phrase 'applejack,' prompting a surge of knowledge about Arno's illicit gambling activities. This revelation sets off a chain of events that puts him in grave danger.

Following the accidental revelation about Arno, Dexter is captured by the businessman’s henchmen. The students quickly realize the implications of their discovery, endangering their safety and the tournament's prospects.

Determined not to let Dexter down, his friends devise a clever plan to rescue him. Disguised as house painters, they infiltrate the captors’ hideout, showcasing their bravery and loyalty to their friend.

In a thrilling escape, Dexter's friends manage to get him out of captivity. Despite sustaining a concussion during the rescue, Dexter realizes that his extraordinary abilities are starting to fade.

With Dexter less capable after his head injury, Schuyler steps in to answer the tournament's final challenge. This crucial moment will determine the outcome of the competition and the fate of Medfield College.

Schuyler answers correctly, stating 'Lebanon, Kansas,' which is the answer to the final question. This response secures the victory for Medfield College, earning them the $100,000 prize.

As Arno attempts to escape after the tournament, chaos ensues when his getaway vehicle crashes into a police car. This unexpected incident leads to Arno's arrest and the suspension of his illegal operations.

Following their triumph, the students at Medfield College celebrate their victory and the successful defeat of Arno. Dexter and his friends rejoice in both their academic success and the bond they share.
