The only British soil occupied by Nazi Germany during the Second World War was a scattering of islands in the English Channel. This film covers the five years Jersey, Guernsey, and their neighbors spent under German control, from the 1940 invasion to the 1945 liberation. Archival footage and photographs sit alongside accounts of islanders who lived through it, tracing the full range of what occupation produced: collaboration with the occupiers, an underground resistance, informants who turned in their neighbors, and deportations to camps on the continent. The film does not flatten the experience into a single story of either heroism or betrayal, showing instead how ordinary shopkeepers, farmers, and officials ended up on opposite sides of the same small islands. Daily life between conquerors and conquered gets as much attention as the dramatic episodes, including how food shortages, curfews, and forced labor reshaped island society. The result is a detailed local case study of what occupation actually does to a community, rather than a broad account of the war.
