Twelve boys and girls live as 1940s war evacuees. The evacuees discover just how scary life in wartime Britain was as they swap chores for building air raid shelters. Will our modern evacuees be up to the job and, more importantly, how will they cope in an actual air raid? After their hard work, it's a good old-fashioned 40s breakfast - kippers. Unfortunately these fish have eyes, but wasting food in wartime was a definite no-no.
