An elementary school teacher named Randi Coy is offered $250,000 for herself and $250,000 for the rest of her family if she takes part in a fake wedding engagement to a man named "Steve Williams," who will also win $250,000 for himself and $250,000 for his family. They have to convince their families of their engagement and get married in 12 days time with all their family members attending and without any of them objecting, in order to win the money. However, what Randi does not know is that Steve is, in reality, a professional actor, whose goal is to make things difficult for Randi. In the first episode, things get complicated as the fake fiance is revealed to be the very annoying and unattractive man who fits the show's title. The revelation of the engagement to Randi's family intentionally causes tension. The episodes after continue to follow Randi, Steve, and the Coys as they prepare for the wedding. To make matters more crazy, the Coys meet Steve's family. On the wedding day, Steve and Randi arrive at the altar and proceed with their vows. Randi says 'I do' and when it comes to Steve's turn, he acts emotional and eventually announces that the whole wedding was a setup. At the same time it is revealed that Steve is in fact actor Steven W. Bailey, and his "family" were also all professional actors – something that even Randi did not know. When Steve reveals that "it's fake" and that he is an actor, Randi begins crying. Because nobody caught on to the entire scheme, and because Randi was unaware that Steve was part of the scam, she and her family were presented with double the amount of money that Randi had expected – $500,000 for herself and $500,000 for her family.
