Grandma?

GERIATRIC ZOMBIES!!! Randall just wanted to have a fun summer vacation with his family, visiting Grandma at her cabin on a lake in the Wisconsin Northwoods. Then everything went horribly wrong. Join fifteen-year-old Randall, and his younger brother Josh, as they fight for their lives on the eve of an elderly undead apocalypse. Grandma? She won't bake you cookies... Forget everything you've ever read about zombies. But that's probably impossible, because you know you've read a lot. So maybe just put aside your preconceptions, because this living dead epic will make you remember why you fell in love with this genre in the first place. Part scary, part funny, this is a living dead Armageddon like you've never seen before.
