Terry Gannon Jr. 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 move in with her estranged father, Terry Sr. aka "The Cannon," an opinionated, beer-guzzling, ex-athlete who never quite made the cut as a single father or professional baseball player. When Terry reluctantly offers to coach Danny and a group of other athletically-challenged hopefuls, her past comes rushing back.
