In October 2013, wildlife cameraman and director Andrew Graham-Brown and assistant producer Ruth Peacey set sail for Antarctica to film a colony of Gentoo penguins for a BBC Natural World film which every year return to Port Lockroy on a tiny island called Goudier to find a mate and raise their young in the shadow of world's most southerly public Post Office. It was to be one of the most challenging filming trips they had ever undertaken. Joining them in Antarctica was wildlife cameraman Doug Allan who narrates this series of five programmes which follows the team's adventures. Having survived the notorious Drake Passage, the team have reached the southern oceans but their troubles aren't over. They are surrounded by sea ice and send the first mate up the mast to help navigate a safe journey through the maze. All goes well until a fierce storm takes them by surprise and once again they endure a terrifying journey until they reach Anvers island and sanctuary for the night. Next morning they set off on the last leg of their journey but instead of reaching Port Lockroy are forced to stop within a few hundred metres of Goudier island by yet more dense sea ice.
