Riley is determined to set Ben up with Zoey, believing they would be perfect together. But both resist her attempts, insisting they don't have feelings for each other. Meanwhile, Tucker auditions to be a local weatherman, but Bonnie inadvertently ruins his chances when she tries to get Danny a job as a sportscaster.

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.
