Melodrama about a bomber on board an airplane, an airport almost closed by snow, and various personal problems of the people involved.

When an entire town in upstate New York is closed down by an unexpected snowfall, a "snow day" begins when a group of elementary school kids, led by Natalie Brandston, try to ensure that the schools stay closed by stopping a mechanical snowplow driver by trying to hijack his plow truck. Meanwhile, Natalie's big brother Hal is using this day to try to win the affections of Claire Bonner, the most popular girl in his high school, while Hal and Natalie's father Tom, a TV meteorologist, faces off against a rival meteorologist for weather coverage of the day's events.

On Christmas Eve, snowplow driver Leo races to clear the streets of Montreal and complete his holiday shopping in time for midnight Mass. The feature directorial debut of celebrated filmmaker Gilles Carle (The Death of a Lumberjack), The Merry World of Leopold Z is an offbeat holiday treat that builds to a disarmingly resonant conclusion.
