It's another Thanksgiving at Grandma's. Gavin expects a long, boring day full of pesky toddlers, but his cousin Rhonda has a different idea: make a break for it to the swing set in the backyard! Gavin isn't so sure, especially when they encounter vicious guard dogs (in homemade sweaters), overly affectionate aunts, and worst of all, the great wall of butts. Can they avoid all the obstacles and find some fun before turkey time?
