Enemy At The Door is a British television drama series made by London Weekend Television for ITV. The series was shown between 1978 and 1980 and dealt with the German occupation of Guernsey, one of the Channel Islands, during the Second World War. The programme generated a certain amount of criticism in Guernsey, particularly for being obviously filmed on Jersey despite being ostensibly set on Guernsey. The series also marked the TV debut of Anthony Head as a member of the island resistance. The theme music was by Wilfred Josephs.

A group of convicts and outcasts fight a guerrilla war against the totalitarian Terran Federation from a highly advanced alien spaceship.
