It's turning out to be a pretty rotten Christmas for the Saunders family. Having just moved to a new city from Los Angeles, they have no friends, no money and, with the exception of the bright-eyed Mary, no Christmas spirit. To make matters worse, their mother is stuck in L.A., stranded by airline overbookings. So, the Christmas shopping duties fall on Dad and the gloomy kids. Things start looking a bit more like Christmas when 12-year-old Brian and 6-year-old Mary find a satchel of money at the local mall and they launch a Yuletide shopping spree... that is, until the crooks who counterfeited the money chase them through the mall packed with holiday shoppers.
