Terry Gannon Jr. (Maggie Lawson) was an All Star softball player until life threw her a couple curve balls: a baby, a lost college scholarship and a loser for a husband. After striking out on her own, Terry and her son Danny (Griffin Gluck) move in with her estranged father, Terry Sr. aka "The Cannon" (James Caan).

The Cannon is an opinionated, beer-guzzling, ex-athlete who never quite made the cut as a single father or professional baseball player. As hard as Terry tries to keep Danny away from the sports-driven lifestyle of her youth, Danny wants to play Little League. His stunning lack of baseball skills (he doesn't even know which hand the mitt goes on) makes him the laughing stock of the baseball field and his grandfather's living room. When Danny and a group of other athletically-challenged hopefuls fail to make the team, Danny's disappointment forces Terry to face her past. So when a wealthy neighbor volunteers to finance a team for the rejected kids, Terry reluctantly offers to coach the team of misfits.
