September 1940. The Blitz has brought the harsh realities of war to the people of London. Houses, factories and railway lines are being bombed nightly by the Luftwaffe, and no family can be confident that their home will not survive another night.
Having narrowly escaped a bombing raid on their own street, young Janet and Tommy Phelps are evacuated to the Isle of Wight, to see out the war with their Aunt Betty and irascible Uncle Ted. The children’s parents, Kath and Brian, believe the island will be a safe haven away from the perils, dust and havoc of a capital under siege.
