May 1942. The small English village of Bramley End is visited by a detachment of about 60 Royal Engineers. They are ostensibly there on an exercise but are in actual fact a detachment of German paratroopers, the advance guard of Hitler's invasion of England. Some of the villagers figure out their true identities but before they can do anything all the villagers are held prisoner by the Germans. Will the villagers be able to get word out of the threat? The fate of England depends on them.
