Henry Rowegartner es un chico de doce años que sueña con jugar al béisbol en los Chicago Cubs. Un día, de manera fortuita, Henry se rompe un brazo y al quitarle la escayola, meses más tarde, el médico comprueba que sus ligamentos se han soldado de manera extraña y le han conferido a su brazo una fuerza descomunal.
