This sitcom follows Terry Gannon Jr. (Maggie Lawson). She was an All Star softball player until life threw her a couple curve balls. She married a loser, had a baby, and lost her college scholarship. Now, Terry and her son Danny (Griffin Gluck) are starting a new life by moving back with Terry’s estranged father, Terry Sr. aka “The Cannon” (James Caan). He’s an opinionated, beer-guzzling ex-athlete who never quite made the cut as a professional baseball player — or a single father. He’s okay with putting up his daughter and grandson for a while — as long as they play by his rules.
