The script, co-written by Marshall and Geena Davis, skillfully weaves together a compelling narrative, balancing humor, drama, and inspiration. The story follows Dottie Hinson (Geena Davis) and Kit Keller (Tom Hanks), two sisters who join the Rockford Peaches, a team in the newly formed AAGPBL. As the team navigates the challenges of professional baseball, the script masterfully explores themes of perseverance, female empowerment, and the breaking of stereotypes.
