Wedding coordinator Faith McKenna doesn't believe in the happily-ever-after that she promises her clients. So she has no qualms about giving a few brides one last fling on the side before they commit for life.

When maid of honor Rachel Union catches her best friend fooling around with the wedding coordinator before her wedding day, she swears she'll out Faith to everyone if the bride doesn't make it down the aisle. Against her better judgment, Rachel agrees not to tell the groom, but she vows to keep a close eye on Faith until after the big day. But spending time with Faith challenges Rachel's opinion of her as shallow and opportunistic.
