The story of Gabriel is based in 1943 Nazi-occupied Guernsey. Widow and mother Jeanne does whatever it takes to keep her adolescent daughter Estelle and daughter-in-law Lily safe on an island filled with danger and fear. Her toughest test arrives in the form of the terrifying Commander Von Pfunz, whose romantic advances may be the only way to keep her family alive. But tensions intensify when a mysterious young man is washed ashore with no memory of who he is. Fluent in German and English, is he an RAF pilot, an SS interrogator, a local boy with amnesia or a saviour sent from heaven? The stakes are high and getting it wrong means certain death.
