Every year, thousands of Antarctica's emperor penguins make an astonishing journey to breed their young. They walk, marching day and night in single file 70 miles into the darkest, driest and coldest continent on Earth. This amazing, true-life tale is touched with humour and alive with thrills. Breathtaking photography captures the transcendent beauty and staggering drama of devoted parent penguins who, in the fierce polar winter, take turns guarding their egg and trekking to the ocean in search of food. Predators hunt them, storms lash them. But the safety of their adorable chicks makes it all worthwhile. So follow the leader... to adventure!!

This documentary follows various migratory bird species on their long journeys from their summer homes to the equator and back, covering thousands of miles and navigating by the stars. These arduous treks are crucial for survival, seeking hospitable climates and food sources. Birds face numerous challenges, including crossing oceans and evading predators, illness, and injury. Although migrations are undertaken as a community, birds disperse into family units once they reach their destinations, and every continent is affected by these migrations, hosting migratory bird species at least part of the year.
