Dee Dee Allen and Barry Glickman are New York City stage stars with a crisis on their hands: their expensive new Broadway show is a major flop that has suddenly flatlined their careers. Meanwhile, in small-town Indiana, high school student Emma Nolan is experiencing a very different kind of heartbreak: the head of the PTA has banned her from attending the prom with her girlfriend, Alyssa. When Dee Dee and Barry decide that Emma's predicament is the perfect cause to help resurrect their public images, they hit the road with Angie and Trent, another pair of cynical actors looking for a professional lift. But when their self-absorbed celebrity activism unexpectedly backfires, the foursome find their own lives upended as they rally to give Emma a night where she can truly celebrate who she is.
