When high school heartthrob and star athlete Cole Jackson breaks Tatum's heart, she makes a pact with herself to never be hurt again. She turns love into a game modeled after her family's favorite pastime: baseball. Anyone brave enough to date her must step up to plate and earn each base by following her rules - or they're out. Years later Cole, as handsome and charming as ever, makes an unexpected reappearance in her life with promises that he's a changed man. He's got the story to prove it and says he's willing to follow all of her rules just to have a second chance. Complicating matters is the strong and steady Airman, Justin Parker, with a heartbreak story of his own. His friendship challenges all she ever knew of loving and being loved. Will Tatum's rules help her navigate two very different men, or will she strike out at her own game?
