Perjury.

Robert Moore is the general manager of the firm run by John Gibson. After Gibson makes several visits to Moore's home, unfounded rumors begin of a relationship between Gibson and Moore's wife, Martha. Moore is discovered with a revolver in his hand, standing over Gibson's dead body. In fact, Moore’s best friend committed the murder, but Moore is convicted of second-degree murder and sentenced to 20 years in prison. Impulsively Martha remarries to a man who proves to be a brute. When Moore is set free after the real murderer confesses, he visits his former wife just as her husband attacks her. In a struggle, Moore shoots him in self-defense and is then reunited with his family.
