Marni (Kristen Bell), a new Vice President of a large Public Relations Agency, is returning home for her brother Will's (James Wolk) wedding. Marni discovers that his bride Joanna (Odette Yustman) is her former arch nemesis in high school who made her life a living hell. Joanna is now an angel in her brother's eyes, absolutely not the memories that Marni has of her tormentor. All of this is compounded by the fact that the bride's wealthy Aunt Romona (Sigourney Weaver) flies into town and comes face to face with Marni's mother Gail (Jamie Lee Curtis), who it turns out has an old high school score to settle with Gail. Marni must protect her brother by showing him Joanna's true colors before he makes the biggest mistake in his life. The claws are about to come out. Douglas Young (the-movie-guy)
