Based on the critically acclaimed book by Sue Halpern and narrated by Academy-nominated Kristin Scott Thomas, The Incredible Story Of The Monarch Butterfly: Four Wings And A Prayer, follows the migration of the Monarch butterfly from its birthplace in Canada to its wintering site in the rainforests of Mexico.

Every autumn, a truly incredible natural event takes place. A Monarch butterfly born in Canada will fly more than 3,000 miles to Mexico, across land it has never seen. Its journey is filled with peril; many never make it and those that do will never return. It takes three more generations to make the journey back the following spring. No generation has ever made the journey before, and will never make it again. The great mystery is how they do it.

The Incredible Story Of The Monarch Butterfly: Four Wings And A Prayer is part of BBC Four's Alien Nation season.
