Al Percolo, a baseball scout, works for the New York Yankees. After discovering a string of promising players who turned out to be disappointments, Al gets relegated to scouting talent in Mexico as punishment. There, he comes across Steve Nebraska, an exceptionally talented but quirky baseball player with a tremendous pitching and hitting ability. Convinced that Steve is a once-in-a-lifetime find, Al brings him back to New York, hoping to revive his own career and help the Yankees win the World Series.

Back in New York, Steve's talent dazzles everyone, but his erratic behavior raises concern. The Yankees demand a psychological evaluation before signing him. Dr. H. Aaron, a sports psychologist, is brought in to assess him. As the psychologist delves deeper into Steve’s past, it becomes evident that his erratic behavior stems from personal trauma. Al and Dr. Aaron must work together to help Steve navigate his psychological issues, while also preparing him for the pressure and expectations of major league baseball.
