Tucker is ordered to appear in court in response to a lawsuit he filed against a construction company, so he hires Riley to be his lawyer. When the company offers Tucker a small settlement, Riley refuses to accept it and demands that Judge Johnson send their case to trial. Once Tucker admits that he can't remember what actually happened, Riley realizes she needs to get creative if she wants her first trial to be a success. Bonnie is shocked that Ben and Danny bought Bar on B and thinks they should sell it because they know nothing about owning a business. She is so convinced the guys are destined to fail that she speeds the process along, starting with a very fake health inspector. Can Ben and Danny overcome their mother-sized obstacles and prove they have what it takes to make Bar on B a success?

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.
