It's June in Boulder, Colorado, and wedding season is in full swing. Parker Valentine is excited to attend the wedding of her favourite cousin, Emma, where in addition to celebrating the happy couple, she'll also be providing the refreshments for the reception from her winery. But when the fussy wedding planner is found dead midway through the ceremony, Parker knows that to get the weekend back on track, she'll need to unveil a murderer. Unfortunately, there's no shortage of high tension and hot tempers during a wedding, so Parker has a long list of potential suspects. Even worse, her entire family has fixated on the state of Parker's relationship with her boyfriend, Reid. If Parker can manage to impress her relatives with her wine skills and dodge unwanted pointed personal questions, solving a murder will be the icing on the cake.
