Best friends and academic overachievers, Amy (Kaitlyn Dever) and Molly (Beanie Feldstein), thought keeping their noses to the grindstone gave them a leg up over their play-minded peers. But, on the eve of their graduation, these type-A ride-or-dies get a hardcore reality check and realize they may have missed out. Determined to make up for lost time, they decide to cram four years of not-to-be missed fun into one night - a chaotic adventure no amount of book smarts could prepare them for.
