Blind Justice 1961

A man is accused of murdering his wife. The state prosecutor assumes he did the deed to spend more time with his lover. But the woman in question says that his wife committed suicide in her presence and that the accused is innocent. Despite the objections of the prosecutor, the accused is set free and is found dead shortly thereafter. The prosecutor decides to pursue the case and comes upon a band of criminals, who sell German state secrets. Shortly before the investigation comes to a close, a woman is murdered. When a witness asserts to have seen him near the woman's dead body, the prosecutor himself ends up in court and must now prove his innocence.
