Katie "Pidge" Holt, at the tender age of twenty-one, was surprised when she got an invitation in the mail from an ex-boyfriend to his wedding. Without a date, she scoped out her potential suckers for one and unfortunately, had ended with her lying and how she had gotten back together with Keith Kogane, her first ex-boyfriend. Now, they're stuck together in a lie and have to fake their way through the wedding as the couple that they haven't been since high school, five years ago.
