Spearhead honours an unsung hero of World War II, Clarence Smoyers, who deplored violence but became the gunner of one of the first Pershing tanks in the European Theatre, spearheading the American invasion of Germany. Smoyers's story is a powerful evocation of the lives and challenges of the 'tankers', so critical to the war effort, as well as of German civilians caught up in the conflict.
Nearly seventy years later, Smoyer and Buck Marsh, his armoured infantry comrade, return to meet the German Panther gunner, Gustav Schaefer, they had defeated at the Battle of Cologne - healing the wounds of World War II.
