This is a film about the work and research being carried out at the South Pole - the White Continent.

Just off the Pembrokeshire coast lie two small islands-Skomer and Skokholm. The inhabitants number many thousands, of which a few are human. The rest include seals, the unique Skomer voles, and above all great colonies of seabirds like guillemots, kittiwakes, and comical-looking puffins. These bird cities are formed when the ocean wanderers of the winter fly in to become the cliff nesters of the summer.
