Plot.
Unhappily married, John Worth Hyndman wants to leave his spouse and her father's company, Triton Realty, where he is a vice president. His wife Linda scoffs and says without his father-in-law, John wouldn't even be able to find a job digging ditches.
Trying to calm down, taking a walk, John happens across a team of actual ditch-diggers from a WPA project. He asks foreman Manuel for a job, but a suspicious Manuel turns the well-dressed stranger down. Manuel's lovely daughter Osa advises the new man to change his appearance. In work clothes, digging voluntarily, John gets the job.
Weeks go by without the workers knowing John's true identity. Osa falls in love with him. Upset by their living conditions at home, Manuel's family protests to the landlord, which turns out to be John's father-in-law, T. J. Triton.
Manuel, Osa and the others feel betrayed when they learn the truth. It takes some doing, but John wins back everyone's trust, makes Triton see the error of his ways and lets a happy Osa know that Linda has left him to get a divorce.
