After losing his parents, who died from grief over their son's unjust sentence to jail, John Redmond obtains his release and devotes his life to the uplift and betterment of mankind. After preaching to a crowd one day he is accused of having served a term in jail himself. The leader of a gang and his followers are planning an act of burglary in a saloon. John Redmond happens into the same place, but he is mocked and leaves. One of the gangsters decides to lead an honest life and appeals to John for moral aid. The lay-preacher tells him his story: How in a quarrel one evening his sweetheart was killed by the bullet of a rival suitor, which was meant for him, and for which he was sentenced to jail. Through the intervention of this prison chaplain, however, the case was retried, his innocence was proven and he was set free. His first way was to his ill mother who, shortly after his return, died in his arms. Nellie, the reformed gangster's sweetheart, rejoices over his reformation, and the lay-preacher continues his life's vocation.
