During WWII, British ace fighter pilot Ned Cuttle shot down a German Heinkel. It was foggy so no one really knew where the downed plane landed. Twenty years later, agents from both the West and East want to find it and will do anything to get there first. John Havoc is coerced into helping Cuttle 'remember'.
