Plot

Peter Ingram is a successful London screenwriter, the creator of one of the most popular television shows in Nazi-occupied Europe, An Englishman's Castle. It is a period soap opera, following an ordinary London family during an imagined German invasion of England in 1940. Ingram is oblivious to Nazi rule, which is hidden behind a façade of seemingly-normal English daily life. The invasion was followed by several years of guerrilla warfare, which ended in a truce with Germany and an amnesty that enabled the resisters to resume normal daily life in return for accepting the reality of German occupation, which they generally did, feeling that further resistance was futile.
