Spikes Randall is about to become the first woman to play Major League Baseball. Armed with an unhittable knuckleball, facing overwhelming odds and blatant sexism, she has worked her way up the minor league ladder to shatter the thickest glass ceiling in sports.
Sitting alone in her makeshift locker room before making her historic pitching debut in front of a stadium packed with fans and celebrities, with tens of millions more watching on their screens, Spikes dictates a message to her hero and inspiration, Jackie Robinson, who broke baseball's shameful color barrier 82 years earlier. Jackie is perhaps the only individual on Earth who can appreciate the pressure Spikes faces.
Failure is not an option, yet success is far from assured for any rookie, let alone a pioneer like Spikes. Sharing her journey, hopes, and fears with Jackie helps calm her nerves while she waits to enter baseball's biggest arena. Can Spikes overcome her anxiety and prove women belong among the world's highest skilled baseball players? Will she be able to blaze a trail for other young girls and women who dream of following in her footsteps?
When Spikes finally takes the mound, she literally holds her future and that of other female ballplayers in her fingertips.
