Return to the Island of Occupation

Two young people staying on the Island of Wight want to return to their German occupied island home, a prospect that seems very unlikely with the war raging all around them. Then they receive word that as a result of their escape, family members are in danger and a captured French resistance worker is going to be shot. They embark upon a dangerous journey to get back before things at home turn very nasty. Can they make it in time through dangerous waters and is God really able to help them?
