Sisters Maura (Amy Poehler) and Kate (Tina Fey) are none too thrilled when their parents tell them they're going to sell their childhood home. They take it upon themselves to throw a massive rager reminiscent of their younger years — that Elle Woods and her sorority sisters would be proud of — to bid farewell to the house. The house party turns into the throwback reunion that this group of adults needs to feel like kids again and gives Maura and Kate a time to bond and remember their younger years when things were a little easier and life was way more fun.
