The pair spend their last week before heading off on their next music tour visiting friends and preparing for the going away party they intend to host. Their apprehensions about throwing the party are universally validated when their divorced mother and father as well as both of their ex-boyfriends converge on the party, leaving tragedy in the wake of what they had envisioned as a unifying celebration. In the aftermath, Elle and Joy are left with the sobering yet liberating truth that they can only rely on one another. Cast also includes Mimi Rodgers Dan Byrd, Amanda Crew, Madeline Zima, Liam Aiken, and Jon Heder. Oscar-nominee Saoirse Ronan narrates the film.
