...and the Sky Above Us(1947)

Original title: ...und über uns der Himmel

Hans Albers plays returning war veteran Hans Richter who has trouble finding work. With nowhere else to turn, Richter gets involved with black market activities. This so disgusts Richter's son, blind ex-soldier Edwin (Paul Edwin Roth), that the boy literally disowns his father. Hans eventually mends his ways, but not before several other devastating setbacks.
