Julie and Sarah Thompson are heading for Grandma's house, even though they don't have her address-or even permission to cross the street without a grown-up! Get in the yuletide spirit as Julie and Sarah spark a madcap romp involving two lighthearted crooks who claim to be Santa's elves, a ransom demand, a mother's love, a million-dollar lottery ticket, pursuing cops, a would-be Santa and his reindeer, Roy Rogers-like heroics and of course, the route to Grandma's house.
