Like many children, Rachael and her little brother Casey love to go to restaurants, but they hate to wait for their food to arrive. The time passes quickly, however, when their father reveals that their apparently mild-mannered grandmother spent her younger days as a Wild West outlaw known as Bubby the Kid. One night, a poker game at the Tombstone Saloon leads to an accusation of cheating, and Bubby the Kid faces the hanging judge. Can Rachael and Casey stop fighting long enough to figure out how to save Bubby the Kid from the long arm of the law?
