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. As the young Gentoo penguins prepare to enter the water for the first time - they face another of life's challenges - leopard seals. These fearsome predators patrol the shores waiting for the young penguins to take their first dive. Doug Allan joins the team to film the hunt that is likely to follow - but Antarctica is an unpredictable place; the bay is filling with ice which deters the seals, the weather becomes worse and time is fast running out before the team must leave Antarctica and head for home.
