Izzy is an energetic 9-year-old. Overscheduled and running late, Izzy's parents can't pick her up on-time the last day of school before Christmas break. A blizzard complicates the matter, but not as much as a pair of bad guys who are freezing in an ice cream truck. The school's janitor is kidnapped by the intruders, and it's up to Izzy to save the day.
