No matter how old you are, you never get over high school. PR pro Marni (Kristen Bell) discovers her older brother's (Jimmy Wolk) is marrying her high school arch nemesis Joanna (Odette Yustman).
Joanna has conveniently forgotten all the rotten things she did so many years ago.
Then the bride's jet-setting aunt (Sigourney Weaver) bursts in and Marni's not-so-jet-setting mum (Jamie Lee Curtis) comes face to face with her own high school rival. The claws come out and old wounds are opened in this crazy comedy about what happens when you're reunited with the one person you'd like to forget.
