What’s a 16-year-old boy to do when he learns that his stepmother and a local judge have murdered his father and now plan to kill him, too? Well, when it’s 1906, and you can play pretty good second base, you join a barn-storming baseball team making its way across Kansas. It also helps that the team is the Kansas City National Bloomer Girls. After all, who’d look for a runaway boy disguised as a girl on a women’s team that competes against town teams of male players?

Of course, it’ll take more than long hair, a Spalding glove, and a quick bat to stay alive. Luckily, another Bloomer Girl, Buckskin Compton, alias Dolly Madison, on the dodge after some shootings and beatings in Wyoming, takes the kid under his tutelage. Staying alive won’t prove easy for the reluctant female impersonators as they deal with a budding romance, hitting slumps, a crooked manager, bean balls, drunken teammates, bank robbers, lousy umpires, a revolution for women’s rights and a rapidly changing Western frontier.
