Eloise McGarry attends the wedding of her oldest friend Francie Millner. It's discovered that she was originally maid of honor but "dropped out" two months ago after her ex boyfriend Teddy, the bride's brother and the best man, broke up with her by text after two years together. Teddy is now back with his old girlfriend Nikki, who has replaced Eloise as maid of honor. At the reception, Eloise discovers she has been seated at Table 19. While she considers leaving early, she meets a man named Huck who notices her looking distressed and offers words of advice which are not well received.
