Don and Donna are twins who share everything, especially their immense love for the game of baseball. Don has spent hours teaching Donna how to pitch, catch, and swing a bat like a true champion. She is arguably the best player in the neighborhood, but there is one giant, unfair rule standing in her way: the local team only allows boys to play. Donna is forced to sit on the sidelines while her brother takes the field. However, when the day of the huge championship game arrives, Don suddenly falls terribly ill and cannot leave his bed. The team desperately needs their star player. Taking a massive risk, Donna secretly tucks her hair under a baseball cap, puts on Don's oversized uniform, and steps up to the plate. You will cheer out loud as Donna proves that true talent has absolutely nothing to do with whether you are a boy or a girl.
