A musical melodrama
The poor man did not start out to be a drunkard; mercy no!
He was the penniless heir of his kindhearted father, from whom he inherited his virtues. He would not be moved by that villain lawyer to kick the widow and her daughter out of their cottage. Indeed, on seeing the fair daughter he proposed.
The wedding of these two paupers does not produce financial relief. One day the lawyer lures the noble husband to a saloon; he becomes a drunkard and the poverty increases.
The lawyer tries to get the husband to forge a name, but he is still too virtuous for that. It's the husband's foster brother who plays detective, finds out what the lawyer is up to, discovers his brother in the slums and helps capture the villain.
With the help of all men of good will, retribution is realized in the end.
