A young Baker with a heart defect, Charlie Kensington enlists in military service shortly before the Normandy D-Day landings in 1945 in search of his brother Alan when he does not return in the evacuation of Dunkirk. Alan leaves behind his artwork, giving Charlie clues as to his whereabouts, whilst Charlie tries his best to navigate his way through German-occupied France and nothing but his rifle and his wit.
