When the cast is removed from his broken arm, clumsy 12-year-old Henry Rowengartner (Thomas Ian Nicholas) is shocked to find his arm has become a 100-mile-per-hour thunderbolt. His throw from the bleachers directly to home plate alerts the last place Chicago Cubs and before you can shout "play ball!" he is signed as their new ace pitcher. With a few pointers from an aging star pitcher (Gary Busey), young Henry actually manages to pull off the impossible. Daniel Stern co-stars in this winning stand-up-and-cheer tale about one boy's dream.
