Two little girls (played by the olsen twins) hear thier mom telling her friend about how much trouble it is to be a single mom raising two little girls, its near christmas time and they figure the best thing to do would be to go have christmas with their grandma.So they run away thinking they are helping their mom, but along the way they get kidknapped by some pretty interesting criminals, walk downtown by themselves, hide in a mail truck, and ride a poney.At the end they get to their grandmas and are reunited with their mom, and, they even win the lottery.
