Danny gets nervous after landing a cameo role on "General Hospital," so he asks soap-opera fan Riley to help him rehearse. Elsewhere, Ben and Tucker assist Bonnie with a scheme to get her back into her old apartment.

Baby Daddy follows Ben, a young man in his early 20s living the life of a bachelor in New York City with his buddy, Tucker, and his brother, Danny. Their lives are turned upside down when they come home one day to find a baby girl left on the doorstep by an ex-girlfriend of Ben's. After much deliberation, Ben decides to raise the baby with the help of his friends and his protective and sometimes over-bearing mother, Bonnie, and his close female friend, Riley.
