It’s Christmas Eve in a typical suburban household — two worn-out parents, and three wildly excited children. In a desperate attempt to get the kids to sleep, their father tells them a homespun bedtime story, an instant Christmas classic — the story of Santa’s little ferrets. Although very few people know it, it seems that Santa brings an elite security detail with him every Christmas Eve — three highly trained ferrets. Their job? Make sure no one’s awake, trying to catch a glimpse of Santa. But on this particular night the unexpected happens, and the line between fantasy and reality becomes blurred. Suddenly, the ferrets’ entire security operation is in jeopardy!
