Robin and Ellie have been best friends since childhood. When Robin came out, Ellie was there for her. When Ellie's father died, Robin had her back. But when Ellie asks Robin to be her maid of honor, she is reluctant. A queer academic, Robin is dubious of the elaborate wedding rituals now sweeping the nation, which go far beyond champagne toasts and a bouquet toss. But loyalty wins out, and Robin accepts. 

Yet, as the wedding weekend approaches, a series of ominous occurrences lead Robin to second-guess her decision. It seems that everyone in the bridal party is out to get her. Perhaps even Ellie herself.
