Former high school friends run into each other years later and drunkenly decide to make good on their promise to marry each other if they're both still single by 30 - only to discover too late all the things they liked about each other when they were younger have changed.

When a wealthy couple can’t decide on a wedding theme, they hire two wedding planners, Taylor and Ben, to compete for the job by proposing two very different styles. As they compete for the lucrative gig, Taylor and Ben playfully sabotage each other’s efforts but are growing closer together than either of them realise.
