Embers (1983)

Even in war, the life of a rich family is different, according to this fictional story about Francois Korb (Armin Müller-Stahl) an arms manufacturer who sold both to the Germans and the Allied forces. Korb's home life is less than ideal, since his wife is having an affair with his brother, and his young son is inseparable from a teddy bear. To remedy the son's situation, the parents take in a little refugee girl as a temporary companion and playmate, and the two children become fast friends -- and when they meet again long after the war, the influence of family is all the more apparent. Meanwhile, the arms dealer will learn the hard way that weapons kill.
