Bill Norris is studying at the Sorbonne in Paris, France when the Nazis occupy the city. Intervening in a Nazi harassment of a citizen, Norris is arrested and sent to a concentration camp. He helps an old man, who eventually confides to Norris that he's the leader of the French Underground and knows the location of an important French General, who has to be safely brought to Africa to continue the battle. Fashioning an all black Grim Reaper outfit, Norris, with help from the French citizenry, rescues the General. The Reaper regularly kills his Nazi foes with his bare hands.
