A documentary on the migratory patterns of birds, shot over the course of several years on all seven continents.
This documentary presents an epic portrait of winter bird migration. Filmed on all seven continents over the course of several years, the footage is brought together into one portrait of a journey that is uniformly arduous for all kinds of different birds. These long and often torturous treks are a matter of survival. Along the way, the birds face dangers both large and small, from man-made waste to a group of hungry crabs. The search for food, good weather, and a place to hatch their young takes this annual cycle of stamina across continents and oceans.
