Sometimes girls just want to have fun, and Mary (Rachel Melvin), Zoe (Cortney Palm) and Jenn (Lexi Atkins) are heading towards a weekend of fun. This trip turns sour fast. First, team No Boys Allowed, Sam (Hutch Dano), Tommy (Jake Weary) and Buck (Peer Gilroy), show up. Then, a foot is chomped off. Leave it to these zombie beavers as they knock down trees and make tunnels. Smyth (Rex Linn) is eating chicken and talking nonsense. RTS wade through the pond and rock with those blue-eyed demon beavers. Jeremy, Collin and La-Mar, with the help of Bill Burr and John Mayer, turn this cabin slumber party into an epic weekend to remember forever. Disclaimer: there are radioactive zombie beavers that want to gnaw all of your faces off, but in an angry adorable sort of way.
