Four Wings and a Prayer is a documentary about one of the world's most beautiful and mysterious creatures: the Monarch butterfly. Nowhere in nature is there a more powerful mix of scientific marvel, awesome beauty, and epic struggle for survival. What scientists are at a loss to fully explain is how the Monarch makes a seemingly impossible three thousand kilometre journey from Canada over mountains, through storms, and across large bodies of water to its small and remote over wintering grounds in the mountains of Mexico. Based on the book by Sue Halpern.
