While coming to terms with his dad’s recent passing in a tractor accident, 13-year-old George McCray is living with his grandparents on their Kansas farm. George misses his mom, Jill, who has moved to Minnesota to deal with her grief, but there is the promise of their reunion at Christmas. George feels needed on the farm as he helps his grateful grandfather Bo with daily chores and comforts his grandmother Cora. He has also made friends with Mary Ann and became attached to Tucker, the smart and friendly dog the McCrays take in when his troubled owner Frank Thorne lands in jail.
Moving into his late grandfather’s house, young Jack inherits the old man’s dog, Skipper (Norm MacDonald) – who can talk! With the sassy pooch’s help, Jack learns that Grandpa left a priceless Spanish treasure hidden somewhere in the town. Jack joins forces with a trio of clever neighbor kids – a goth girl, a socialite, and a jokester – to find the valuable booty, with Skipper leading the way. But can they outrun the brazen, bumbling thieves that will stop at nothing to seize the prize for themselves?
