synopsis

This is the real-life story of Fred and Norah Urquhart, two Canadian scientists whose life work was the discovery of the annual migratory route of the monarch butterfly. From their Toronto laboratory, it took them more than 40 years to solve this mystery and track the amazing migration from Texas to Toronto with a stop in central Mexico. Theirs is considered "one of the greatest natural discoveries of our time.” In the film, natural history is interlaced with a somewhat scientific detective story about the discovery of places where the butterflies spend their winters in the remote mountains of Mexico.
