Gavin, preparing for a boring Thanksgiving Day with his relatives, joins his cousin's effort to escape to the swing set in the backyard, a journey marked by sweater-wearing dogs, affectionate aunts, and grownups of inconvenient height. It is another Thanksgiving at Grandma's. Gavin expects a long day of boredom and being pestered by distantly related toddlers, but his cousin Rhonda has a different idea.
