Der Winter, der ein Sommer war(1976)

Der Winter, der ein Sommer war is a German historical drama set in 1775 during the American Revolution. When a Hessian officer deserts from Ziegenhayn fortress, Captain Claus von Haynau pursues him relentlessly. The fugitive turns out to be Soermann, a man who vanished two decades earlier and was thought dead—and who holds the key to a family secret. Robert, Claus's half-brother, learns that his father didn't perish but fled to America. Determined to reunite with him, Robert plans his own escape, unaware that Claus will stop at nothing to prevent it. Caught between family loyalty and military duty, the brothers face mounting pressure as the Landgrave of Hesse demands soldiers to sell to the British for their war against the American colonists. Ambition, betrayal, and the pull of a new world collide in this tale of divided allegiances.
