Der weite Weg (1946)

Shortly before the end of the war: Disillusioned Austrian soldiers crammed into a barracks in a prison camp welcome a new arrival who has nothing better to do than rave to the men, who have been separated from their homeland for years, about his Viennese lover. When the womanizer mentions the name of his latest love affair, Manhardt, her husband, jumps at him in outrage; the adulterer falls and dies. Acquitted of murder and returned to Vienna, Manhardt cannot get over his Anni's infidelity. Friends and a second fateful coincidence help.
