Vlak na de verovering van Frankrijk in 1940 bezetten de Duitsers ook de Kanaaleilanden, gelegen tussen Frankrijk en Engeland. Het verhaal vindt plaats op St. Gregory, een fictief eiland behorend tot die eilandengroep. Hier beleven allerlei bewoners op hun manier de bezetting. Hun woede over de oorlog en de bezetting moet geregeld plaatsmaken voor pragmatisme om de Duitsers te vriend te houden en om zelf te kunnen overleven.

Island at War is a British television series that tells the story of the German Occupation of the Channel Islands. It primarily focuses on three local families: the upper class Dorrs, the middle class Mahys and the working class Jonases, and four German officers. The fictional island of St. Gregory serves as a stand-in for the real-life islands Jersey and Guernsey, and the story is compiled from the events on both islands.

Produced by Granada Television in Manchester, Island at War had an estimated budget of £9,000,000 and was filmed on location in the Isle of Man from August 2003 to October 2003. When the series was shown in the UK, it appeared in six 70-minute episodes.
