In the Antarctic, every March since the beginning of time, the quest begins to find the perfect mate and start a family. This courtship will begin with a long journey - a journey that will take them hundreds of miles across the continent by foot, one by one in a single file. They will endure freezing temperatures, in brittle, icy winds and through deep, treacherous waters. They will risk starvation and attack by dangerous predators, under the harshest conditions on earth, all to find true love.
